  • ul sortables get serialized data

    - by russp
    Hi folks Any ideas how to get the serilized data from this function? the html is first with the JQuery function last, I cannot get the serialization to appear in the alert. When I can do that I can finish this by sending via ajax etc... <div class="column" id="col1"> <div class="portlet"> <div class="portlet-header">Feeds</div> <div class="portlet-content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit</div> </div> <div class="portlet"> <div class="portlet-header">News</div> <div class="portlet-content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit</div> </div> Shopping Lorem ipsum dolor sit amet, consectetuer adipiscing elit Links Lorem ipsum dolor sit amet, consectetuer adipiscing elit Images Lorem ipsum dolor sit amet, consectetuer adipiscing elit $(function() { $("#col1, #col2, #col3").sortable({ connectWith: '.column', receive : function () { serial = $('#col1').sortable('serialize'); //serial2 = $('#col2').sortable('serialize'); //serial3 = $('#col3').sortable('serialize'); alert(serial); } }); });

  • Best practice - logging events (general) and changes (database)

    - by b0x0rz
    need help with logging all activities on a site as well as database changes. requirements: * should be in database * should be easily searchable by initiator (user name / session id), event (activity type) and event parameters i can think of a database design but either it involves a lot of tables (one per event) so i can log each of the parameters of an event in a separate field OR it involves one table with generic fields (7 int numeric and 7 text types) and log everything in one table with event type field determining what parameter got written where (and hoping that i don't need more than 7 fields of a certain type, or 8 or 9 or whatever number i choose)... example of entries (the usual things): [username] login failed @datetime [username] login successful @datetime [username] changed password @datetime, estimated security of password [low/ok/high/perfect] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] changed profile name from [old name] to [new name] @datetime [username] verified name with [credit card type] credit card @datetime datbase table [table name] purged of old entries @datetime via automated process etc... so anyone dealt with this before? any best practices / links you can share? i've seen it done with the generic solution mentioned above, but somehow that goes against what i learned from database design, but as you can see the sheer number of events that need to be trackable (each user will be able to see this info) is giving me headaches, BUT i do LOVE the one event per table solution more than the generic one. any thoughts? edit: also, is there maybe an authoritative list of such (likely) events somewhere? thnx stack overflow says: the question you're asking appears subjective and is likely to be closed. my answer: probably is subjective, but it is directly related to my issue i have with designing a database / writing my code, so i'd welcome any help. also i tried narrowing down the ideas to 2 so hopefully one of these will prevail, unless there already is an established solution for these kinds of things.

  • MySQL Database Design with Internationalization

    - by Some name
    Hello, I'm going to start work on a medium sized application, and i'm planning it's db design. One thing that I'm not sure about is this. I will have many tables which will need internationalization, such as: "membership_options, gender_options, language_options etc" Each of these tables will share common i18n fields, like: "title, alternative_title, short_description, description" In your opinion which is the best way to do it? Have an i18n table with the same fields for each of the tables that will need them? or do something like: Membership table Gender table ---------------- -------------- id | created_at id | created_at 1 - 22.03.2001 1 - 14.08.2002 2 - 22.03.2001 2 - 14.08.2002 General translation table ------------------------- record_id | table_name | string_name | alternative_title| .... |id_language 1 - membership regular null 1 (english) 1 - membership normale null 2 (italian) 1 - gender man null 1(english) 1 -gender uomo null 2(italian) This would avoid me repeating something like: membership_translation table ----------------------------- membership_id | name | alternative_title | id_lang 1 regular null 1 1 normale null 2 gender_translation table ----------------------------- gender_id | name | alternative_title | id_lang 1 man null 1 1 uomo null 2 and so on, so i would probably reduce the number of db tables, but i'm not sure about performance.I'm not much of a DB designer, so please let me know.

  • django join-like expansion of queryset

    - by jimbob
    I have a list of Persons each which have multiple fields that I usually filter what's upon, using the object_list generic view. Each person can have multiple Comments attached to them, each with a datetime and a text string. What I ultimately want to do is have the option to filter comments based on dates. class Person(models.Model): name = models.CharField("Name", max_length=30) ## has ~30 other fields, usually filtered on as well class Comment(models.Model): date = models.DateTimeField() person = models.ForeignKey(Person) comment = models.TextField("Comment Text", max_length=1023) What I want to do is get a queryset like Person.objects.filter(comment__date__gt=date(2011,1,1)).order_by('comment__date') send that queryset to object_list and be able to only see the comments ordered by date with only so many objects on a page. E.g., if "Person A" has comments 12/3/11, 1/2/11, 1/5/11, "Person B" has no comments, and person C has a comment on 1/3, I would see: "Person A", 1/2 - comment "Person C", 1/3 - comment "Person A", 1/5 - comment I would strongly prefer not to have to switch to filtering based on Comments.objects.filter(), as that would make me have to largely repeat large sections of code in the both the view and template. Right now if I tried executing the following command, I will get a queryset returning (PersonA, PersonC, PersonA), but if I try rendering that in a template each persons comment_set will contain all their comments even if they aren't in the date range. Ideally they're would be some sort of functionality where I could expand out a Person queryset's comment_set into a larger queryset that can be sorted and ordered based on the comment and put into a object_list generic view. This normally is fairly simple to do in SQL with a JOIN, but I don't want to abandon the ORM, which I use everywhere else.

  • convert xml document to comma delimited (CSV) file using xslt stylesheet.

    - by Brad H
    I need some assistance converting an xml document to a CSV file using an xslt stylesheet. I am trying to use the following xsl and I can't seem to get it right. I want my comma delimited file to include column headings, followed by the data. My biggest issues are removing the final comma after the last item and inserting a carriage return so each group of data appears on a separate line. I have been using XML Notepad. <xsl:template match="/"> <xsl:element name="table"> <xsl:apply-templates select="/*/*[1]" mode="header" /> <xsl:apply-templates select="/*/*" mode="row" /> </xsl:element> </xsl:template> <xsl:template match="*" mode="header"> <xsl:element name="tr"> <xsl:apply-templates select="./*" mode="column" /> </xsl:element> </xsl:template> <xsl:template match="*" mode="row"> <xsl:element name="tr"> <xsl:apply-templates select="./*" mode="node" /> </xsl:element> </xsl:template> <xsl:template match="*" mode="column"> <xsl:element name="th"> <xsl:value-of select="translate(name(.),'qwertyuiopasdfghjklzxcvbnm_','QWERTYUIOPASDFGHJKLZXCVBNM ')" /> </xsl:element>, </xsl:template> <xsl:template match="*" mode="node"> <xsl:element name="td"> <xsl:value-of select="." /> </xsl:element>, </xsl:template>

  • Is there any way to filter certain things in pages served by IIS?

    - by Ruslan
    Hello, This is my first time posting here so please keep that in mind... I'll try to be short and get right to defining the problem. We have an ASP.NET 2 application (eCommerce package) running on IIS (Windows Server 2003). The main site's page(s) are using plain HTTP (no SSL), but the whole checkout process and the shopping cart page is using SSL (HTTPS). Now, the problem is that the site's header is located in a template file, and inside it it has a plain HTML 'img' tag calling an image with the "http://" portion hard-coded into it... This header appears on absolutely every page (including the https pages), and due to its insecure image tag, a warning box pops up in IE on every stage of the checkout process... Now, the problem: The live application cannot be touched in any way (no changes can be made to the template (so simply changing "http://" to "//" is not an option), IIS cannot be restarted, and the website/app pool cannot be restarted). Is there any way in the world (maybe plugin for IIS or a setting somewhere) that I can filter the pages right before they are served to replace the '<img src="http://example.com/image.jpg">' with '<img src="//example.com/image.jpg">' in the final HTML? Possibly via a regular expression or something? Thanks to everybody in advance.

  • CakePHP hasMany relationship with multiple columns

    - by Muhammad Yasir
    Hi, I am using CakePHP framework to build a web application. The simplest form of my problem is this: I have a users table and a messages table with corresponding models. Messages are sent from a user to another user. So messages table has columns from_id and to_id in it, both referencing to id of users. I am able to link Message model to User model by using $belongsTo but I am unable to link User model with Message model (in reverse direction) by using $hasMany in the same manner. var $hasMany = array( 'From' => array( 'className' => 'Message', 'foreignKey' => 'from_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ), 'To' => array( 'className' => 'Message', 'foreignKey' => 'to_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ) ); What can do here? Any ideas? Thanks for any help.

  • Why this class assignment is not working in IE

    - by user550750

  • Render multiple Form instances

    - by vorpyg
    I have a simple application where users are supposed to bet on outcome of a match. A match consists of two teams, a result and a stake. Matches with teams are created in the Django admin, and participants are to fill in result and stake. The form must be generated dynamically, based on the matches in the database. My idea is to have one (Django) Form instance for each match and pass these instances to the template. It works fine when I do it from django shell, but the instances aren't rendered when I load my view. The form looks like this: class SuggestionForm(forms.Form): def __init__(self, *args, **kwargs): try: match = kwargs.pop('match') except KeyError: pass super(SuggestionForm, self).__init__(*args, **kwargs) label = match self.fields['result'] = forms.ChoiceField(label=label, required=True, choices=CHOICES, widget=forms.RadioSelect()) self.fields['stake'] = forms.IntegerField(label='', required=True, max_value=50, min_value=10, initial=10) My (preliminary) view looks like this: def suggestion_form(request): matches = Match.objects.all() form_collection = {} for match in matches: f = SuggestionForm(request.POST or None, match=match) form_collection['match_%s' % match.id] = f return render_to_response('app/suggestion_form.html', { 'forms': form_collection, }, context_instance = RequestContext(request) ) My initial thought was that I could pass the form_collection to the template and the loop throught the collection like this, but id does not work: {% for form in forms %} {% for field in form %} {{ field }} {% endfor %} {% endfor %} (The output is actually the dict keys with added spaces in between each letter - I've no idea why…) It works if I only pass one Form instance to the template and only runs the inner loop. Suggestions are greatly appreciated.

  • SQL Query Math Gymnastics

    - by keruilin
    I have two tables of concern here: users and race_weeks. User has many race_weeks, and race_week belongs to User. Therefore, user_id is a fk in the race_weeks table. I need to perform some challenging math on fields in the race_weeks table in order to return users with the most all-time points. Here are the fields that we need to manipulate in the race_weeks table. races_won (int) races_lost (int) races_tied (int) points_won (int, pos or neg) recordable_type(varchar, Robots can race, but we're only concerned about type 'User') Just so that you fully understand the business logic at work here, over the course of a week a user can participate in many races. The race_week record represents the summary results of the user's races for that week. A user is considered active for the week if races_won, races_lost, or races_tied is greater than 0. Otherwise the user is inactive. So here's what we need to do in our query in order to return users with the most points won (actually net_points_won): Calculate each user's net_points_won (not a field in the DB). To calculate net_points, you take (1000 * count_of_active_weeks) - sum(points__won). (Why 1000? Just imagine that every week the user is spotted a 1000 points to compete and enter races. We want to factor-out what we spot the user because the user could enter only one race for the week for 100 points, and be sitting on 900, which we would skew who actually EARNED the most points.) This one is a little convoluted, so let me know if I can clarify further.

  • How do I relate two models/tables in Django based on non primary non unique keys?

    - by wizard
    I've got two tables that I need to relate on a single field po_num. The data is imported from another source so while I have a little bit of control over what the tables look like but I can't change them too much. What I want to do is relate these two models so I can look up one from the other based on the po_num fields. What I really need to do is join the two tables so I can do a where on a count of the related table. I would like to do filter for all Order objects that have 0 related EDI856 objects. I tried adding a foreign key to the Order model and specified the db_column and to_fields as po_num but django didn't like that the fact that Edi856.po_num wasn't unique. Here are the important fields of my current models that let me display but not filter for the data that I want. class Edi856(models.Model): po_num = models.CharField(max_length=90, db_index=True ) class Order(models.Model): po_num = models.CharField(max_length=90, db_index=True) def in_edi(self): '''Has the edi been processed?''' return Edi856.objects.filter(po_num = self.po_num).count() Thanks for taking the time to read about my problem. I'm not sure what to do from here.

  • GNU Make - Dependencies on non program code

    - by Tim Post
    A requirement for a program I am writing is that it must be able to trust a configuration file. To accomplish this, I am using several kinds of hashing algorithms to generate a hash of the file at compile time, this produces a header with the hashes as constants. Dependencies for this are pretty straight forward, my program depends on config_hash.h, which has a target that produces it. The makefile looks something like this : config_hash.h: $(SH) genhash config/config_file.cfg > $(srcdir)/config_hash.h $(PROGRAM): config_hash.h $(PROGRAM_DEPS) $(CC) ... ... ... I'm using the -M option to gcc, which is great for dealing with dependencies. If my header changes, my program is rebuilt. My problem is, I need to be able to tell if the config file has changed, so that config_hash.h is re-generated. I'm not quite sure how explain that kind of dependency to GNU make. I've tried listing config/config_file.cfg as a dependency for config_hash.h, and providing a .PHONY target for config_file.cfg without success. Obviously, I can't rely on the -M switch to gcc to help me here, since the config file is not a part of any object code. Any suggestions? Unfortunately, I can't post much of the Makefile, or I would have just posted the whole thing.

  • How to suppress jqgrid from initially loading data?

    - by Steve Johnston
    I have a page that has a couple of jqGrids on it, along with a few other fields. I want to make one AJAX call myself that pulls back a JSON object that has the data that should be used to fill the entire page. So, I would like to make the call myself, populate the "other fields" and then pull a couple of collections off of the main JSON object that was returned and populate each of the jqGrids with those collections "manually". I have this much working, but I can't get jqGrid to stop attempting to make an AJAX request itself. Shouldn't there be a way to tell jqGrid to NOT attempt an AJAX call when it is initialized? I found a similar question asked here: http://stackoverflow.com/questions/1850159/how-to-suppress-jqgrid-from-initially-loading-data But I don't have the option that solved it for the poster. It seems pretty logical to me that some people may want to use this plugin without having the table attempt to get its own data upon initialization. Am I missing an option somewhere in the documentation (wiki - options)? Thanks.

  • How to get OCI lib to work on red hat machine to work with R Oracle?

    - by Matt Bannert
    I need to get OCI lib working on my rhel 6.3 machine and I am experiencing some trouble with OCI headers files that can't be found. I have installed (using yum install) oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm because this official page it's all I need to run OCI. To test the whole thing in general I've installed sqplus64, which worked after I set export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib. Unfortunately the headers files couldn't be found after setting LD_LIBRARY_PATH. Actually I am not surprised because there is no include directory in any of these oracle paths. So the question is: Where do I get these missing header files from? Are they actually already there and I just can find them? Btw: I am doing this whole exercise because I want to use ROracle on my R Studio server and this R package depends on the OCI library. Once I am back in R territory the road gets much less bumpier for me. EDIT: this documentation helped me a little further. However, I guess I found some header files now in: "/usr/include/oracle/11.2/client64". But which variable do I have to set to this location?

  • Submit form with POST data in Android app

    - by datguywhowanders
    I've been searching the web for a way to do this for about a week now, and I just can't seem to figure it out. I'm trying to implement an app that my college can use to allow users to log in to various services on the campus with ease. The way it works currently is they go to an online portal, select which service they want, fill in their user name and pwd, and click login. The form data is sent via post (it includes several hidden values as well as just the user name and pwd) to the corresponding login script which then signs them in and loads the service. I've been trying to come at the problem in two ways. I first tried a WebView, but it doesn't seem to want to support all of the html that normally makes this form work. I get all of the elements I need, fields for user and pwd as well as a login button, but clicking the button doesn't do anything. I wondered if I needed to add an onclick handler for it, but I can't see how as the button is implemented in the html of the webview not using a separate android element. The other possibility was using the xml widgets to create the form in a nice relative layout, which seems to load faster and looks better on the android screen. I used EditText fields for the input, a spinner widget for the service select, and the button widget for the login. I know how to make the onclick and item select handlers for the button and spinner, respectively, but I can't figure out how to send that data via POST in an intent that would then launch a browser. I can do an intent with the action url, but can't get the POST data to feed into it. Anyone have any suggestions?

  • SQL Databases and table design/organization

    - by John McMullen
    (NOOB disclaimer) I'm working on a system (a type of map), that is accessed mostly via 3 fields: ID (auto incremented), X coordinate, and Y coordinate. As it is right now, i have all data on the map, stored in 1 table. Whenever the map display is loaded it simply queries the database for contents in x and y, and the DB gives the data (other fields in the same entry). If an item on the map is doing something, it has a flag saying its doing something, and then has an ID of the action in another table holding that type of 'actions'. Essentially, for all map data, its stored in 1 table. All actions of a certain type are stored in their own table. I'm a noob, and i'm wondering what the most effective/efficient structure for such a design? (a map that has items, and each item has stats/actions). I'm using PHP atm, using standard SQL queries to get my data. Should i split up the tables so that there are only x number of entries on a table? (coord range limits)? Should it just keep growing and growing? There's a lot of queries to the table... so just tryin to see what is best :/

I have the following and I would like to insert the indicated code: public class Person { Set<String> updatedFields = new LinkedHashSet<String>(); String firstName; public String getFirstName(){ return firstName; } boolean isFirstNameChanged = false; // Insert public void setFirstName(String firstName){ if( !isFirstNameChanged ){ // Insert isFirstNameChanged = true; // Insert updatedFields.add("firstName"); // Insert } // Insert this.firstName = firstName; } } I'm also not sure if I can the subset of the method name as a string from inside the method itself as indicated on the line where I add the fieldName as a string into the set of updated fields: updatedFields.add("firstName");. And I'm not sure how to insert fields into a class where I add the boolean field that tracks if the field has been modified or not before (for efficiency to prevent having to manipulate the Set): boolean isFirstNameChanged = false; It seems to most obvious answer to this would be to use code templates inside eclipse, but I'm concerned about having to go back and change the code later.

  • What makes good web form styling for business applications?

    - by ProfK
    Styling forms (form elements) is something that even Eric Meyer prefers to avoid. However, most business forms, and that is where styling is at issue; 'contact us' forms are easy to style, put window estate at a premium, with more 'document level' (e.g. invoice) fields, plus 'detail level' (e.g. invoice line) fields. Factors I often find at play are: At my minimum, at least two horizontally adjacent fieldsets are required. In applications vs. public web pages, fixed positioning vs fluid layout is often better. Quantity of content is important, vs. exaggerated readability. Users know the system, and cues etc. take a back seat. In light of factors like these, is there any available guidence for styling web form based applications? Are there any CSS or JavaScript frameworks that would make my quest to style these applications better than Visual Studios still pathetic 'Auto-format' (what drugs were those people on? I will never take them.)

  • Flexible forms and supporting database structure

    - by sunwukung
    I have been tasked with creating an application that allows administrators to alter the content of the user input form (i.e. add arbitrary fields) - the contents of which get stored in a database. Think Modx/Wordpress/Expression Engine template variables. The approach I've been looking at is implementing concrete tables where the specification is consistent (i.e. user profiles, user content etc) and some generic field data tables (i.e. text, boolean) to store non-specific values. Forms (and model fields) would be generated by first querying the tables and retrieving the relevant columns - although I've yet to think about how I would setup validation. I've taken a look at this problem, and it seems to be indicating an EAV type approach - which, from my brief research - looks like it could be a greater burden than the blessings it's flexibility would bring. I've read a couple of posts here, however, which suggest this is a dangerous route: How to design a generic database whose layout may change over time? Dynamic Database Schema I'd appreciate some advice on this matter if anyone has some to give regards SWK

  • How can I prevent a page to jump to top position after failed validation?

    - by Slauma
    I have a simple aspx page with a few TextBoxes and a submit button. Some fields are required and below the button is a ValidationSummary. The complete form is larger than screen height so one has to scroll down to reach the submit button. If I don't fill all required fields and click on submit validation fails as expected and the validation summary displays some info messages below the button. Validation happens on the client and no postback occurs. So this all works as wished. But disturbing is that the page moves ("jumps") to top position when I click on the submit button. To see the validation summary one has to move down the page again. I've tried to set the ShowSummary property to false (which doesn't make much sense): The validation still works (no postback) but in this case the page does not move to top position. So the problem seems to depend on rendering the validation texts. Is there a way to prevent this page jump? Thank you in advance!

  • Using Interop.Word, is there a way to do a replace (using Find.Execute) and keep the original text's

    - by AJ
    I'm attempting to write find/replace code for Word documents using Word Automation through Interop.Word (11.0). My documents all have various fields (that don't show up in Document.Fields) that are surrounded with brackets, eg., <DATE> needs to be replaced with DateTime.Now.Format("MM/dd/yyyy"). The find/replace works fine. However, some of the text being replaced is right-justified, and upon replacement, the text wraps to the next line. Is there any way that I can keep the justification when I perform the replace? Code is below: using Word = Microsoft.Office.Interop.Word; Word.Application wordApp = null; try { wordApp = new Word.Application {Visible = false}; //.... open the document .... object unitsStory = Word.WdUnits.wdStory; object moveType = Word.WdMovementType.wdMove; wordApp.Selection.HomeKey(ref unitsStory, ref moveType); wordApp.Selection.Find.ClearFormatting(); wordApp.Selection.Find.Replacement.ClearFormatting(); //tried removing this, no luck object replaceTextWith = DateTime.Now.ToString("MM/dd/yyyy"); object textToReplace = "<DATE>"; object replaceAll = Word.WdReplace.wdReplaceAll; object typeMissing = System.Reflection.Missing.Value; wordApp.Selection.Find.Execute(ref textToReplace, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing, ref replaceTextWith, ref replaceAll, ref typeMissing, ref typeMissing, ref typeMissing, ref typeMissing); // ... save quit etc.... } finally { //clean up wordApp } TIA.
