  • Help me understand dynamic layouts in Sinatra

    - by thermans
    Help me understand this; I'm learning Sinatra (and Rails for that matter, er, and Ruby). Say I'm doing a search app. The search form is laid out in one div, and the results will be laid out in another. The search form is rendered into the div by a previous view (maybe from a login form). I want to process the form params, perform the search, and render the results into the results div. If I have a single "yield" in the layout and render the divs from different views, the results div erases the search div when it renders. If I define the divs in the default layout, then just render the content, obviously the layout will be messed up: there would have to be two "yields" and I don't think Sinatra supports passing blocks in to yields. I tried foca's sinatra-content-for plugin, and that seems closer to what I need. But I can't figure out where to place the "yield_content" statements. If I have this haml in my layout: #search -# search form = yield_content :search #results -# search results = yield_content :results ... this in my search view: - content_for :search do %form{:method => "post"... etc. ... and this in the results view: - content_for :results do %table{:class => 'results'... etc. This sort of works but when I render the results view, the search div is emptied out. I would like to have it remain. Am I doing something wrong? How should I set this up?

  • Securing against dynamic linking in .NET

    - by Henri
    I want to deploy an application with a license attached. However, I want to prevent that my dll can be easily referenced in visual studio. What are the usual ways of doing this? I was thinking about ngen-ing the application to prevent this, however, then the code becomes architecture dependent. Im not targetting any other architecture/platform besides windows, however, ngen-ing the application after making a release build seems like a workaround to me. Are there any other techniques to achieve this?

  • Handling dynamic data from javascript or rails

    - by 99miles
    I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.

  • How to store dynamic references to parts of a text

    - by Antoine L
    In fact, my question concerns an algorithm. I need to be able to attach annotations to certain parts of a text, like a word or a group of words. The first thing that came to me to do so is to store the position of this part (indexes) in the text. For instance, in the text 'The quick brown fox jumps over the lazy dog', I'd like to attach an annotation to 'quick brown fox', so the indexes of the annotation would be 4 - 14. But since the text is editable (other annotations could provoke a modification from text's author), the annoted part is likely to move (the indexes could change). In fact, I don't know how to update the indexes of the annoted part. What if the text becomes 'Everyday, the quick brown fox jumps over the lazy dog' ? I guess I have to watch every change of the text in the front-end application ? The front-end part of the application will be HTML with Javascript. I will be using PHP to develop the back-end part and every text and annotation will be stored in a database.

  • Python logger dynamic filename

    - by sharjeel
    I want to configure my Python logger in such a way so that each instance of logger should log in a file having the same name as the name of the logger itself. e.g.: log_hm = logging.getLogger('healthmonitor') log_hm.info("Testing Log") # Should log to /some/path/healthmonitor.log log_sc = logging.getLogger('scripts') log_sc.debug("Testing Scripts") # Should log to /some/path/scripts.log log_cr = logging.getLogger('cron') log_cr.info("Testing cron") # Should log to /some/path/cron.log I want to keep it generic and dont want to hardcode all kind of logger names I can have. Is that possible?

  • maintain dialog center with dynamic content

    - by mcgrailm
    I would have a dialog with the following $("#statusbox").dialog({ autoOpen: false, bgiframe: true, modal: true, width: 'auto', height:'auto', title:"Check Order Status", buttons: { Find: function() { get_status(); }, Close: function() { $(this).dialog('close'); } } }); and when the user hits the find button it runs ajax and returns orders to the dialog and it get dynamically re-sized but it only extends the box down. Is there way to make the box extend up and down so that the dialog remains centered ? also if there was enough content then it could potentially go beyond the bounds of the page so I would think I could use a max height to prevent that but what do I do if they re-size the window ? thanks for any help

  • Symfony dynamic forms

    - by Asier
    Hi there, I started with a form, which is made by hand because of it's complexity (it's a javascript modified form, with sortable parts, etc). The problem is that now I need to do the validation, and it's a total mess to do it from scratch in the action using the sfValidator* classes. So, I am thinking to do it using sfForm so that my form validation and error handling can be done more easier and so I can reuse this form for the Edit and Create pages. The form is something like this: <form> <input name="form[year]"/> <textarea name="form[description]"></textarea> <div class="sortable"> <div class="item"> <input name="form[items][0][name]"/> <input name="form[items][0][age]"/> </div> <div class="item"> <input name="form[items][1][name]"/> <input name="form[items][1][age]"/> </div> </div> </form> The thing is that the sortable part of the form can be expanded from 2 to N elements on the client side. So that it has variable items quantity which can be reordered. How can I approach this problem? Any ideas are welcome, thank you. :)

  • Add dynamic URL (or button) to each node in Drupal

    - by Bryan Folds
    I've used CCK to create a 'Travel Offer' content-type which basically just lists the details for a travel package. My question is how to have a button or link on each node (when the user views it) that will link to a url that includes the title of the current node (eg: example.com/requestQuote/Title_Of_This_Node). I haven't implemented my system yet so I am free to change the content-type to include a button field or something like that...

  • Dynamic data-entry value store

    - by simendsjo
    I'm creating a data-entry application where users are allowed to create the entry schema. My first version of this just created a single table per entry schema with each entry spanning a single or multiple columns (for complex types) with the appropriate data type. This allowed for "fast" querying (on small datasets as I didn't index all columns) and simple synchronization where the data-entry was distributed on several databases. I'm not quite happy with this solution though; the only positive thing is the simplicity... I can only store a fixed number of columns. I need to create indexes on all columns. I need to recreate the table on schema changes. Some of my key design criterias are: Very fast querying (Using a simple domain specific query language) Writes doesn't have to be fast Many concurrent users Schemas will change often Schemas might contain many thousand columns The data-entries might be distributed and needs syncronization. Preferable MySQL and SQLite - Databases like DB2 and Oracle is out of the question. Using .Net/Mono I've been thinking of a couple of possible designs, but none of them seems like a good choice. Solution 1: Union like table containing a Type column and one nullable column per type. This avoids joins, but will definitly use a lot of space. Solution 2: Key/value store. All values are stored as string and converted when needed. Also use a lot of space, and of course, I hate having to convert everything to string. Solution 3: Use an xml database or store values as xml. Without any experience I would think this is quite slow (at least for the relational model unless there is some very good xpath support). I also would like to avoid an xml database as other parts of the application fits better as a relational model, and being able to join the data is helpful. I cannot help to think that someone has solved (some of) this already, but I'm unable to find anything. Not quite sure what to search for either... I know market research is doing something like this for their questionnaires, but there are few open source implementations, and the ones I've found doesn't quite fit the bill. PSPP has much of the logic I'm thinking of; primitive column types, many columns, many rows, fast querying and merging. Too bad it doesn't work against a database.. And of course... I don't need 99% of the provided functionality, but a lot of stuff not included. I'm not sure this is the right place to ask such a design related question, but I hope someone here has some tips, know of any existing work, or can point me to a better place to ask such a question. Thanks in advance!

  • Dynamic columns/rows

    - by Fuego DeBassi
    Wondering--does anyone know of any good articles explaining the CSS technique allowing multiple instances of a class to flow down the page relative to the items above it. Not explaining it that well. Veerle' Pierter's does it on this page: http://veerle.duoh.com/belgiangraphicdesign Although I'm not sure I want to use a technique like her's that requires entering of the height per element via her EE installation. I made a little graphic of what I am trying to acheive; http://cl.ly/71163510ce9d294f9f33 The key is I need a robust technique for doing it. Something where the markup could be as simple as; <div class="box"> Number 1 </div> <div class="box"> Number 2 </div> <div class="box"> Number 3 </div> <div class="box"> Number 4 </div> <div class="box"> Number 5 </div> ... Would love any pointers in the right direction.

  • ASP.NET MVC based CMS - dynamic generation of form helpers

    - by user252160
    I am working on an ASP.NET MVC based CMS that presents a rather extreme case. The system must allow the user to add custom content types based on different fields, and for every field, one can add options and validations. The thing is that everything is stored in a complex DB and extracted at runtime using LINQ. I am pretty fresh with ASPNET MVC so the following dilemma came to mind How should I make the content creation view so that form helpers are not predefined int he view code but are loaded based on the type of the field ? Do I have to create a factory class that checks the value of the type property of the field, and then returns a helper based on that or there's a better way to do it. This one seems pretty rigid to me , because anytime I make a change in the Fieldtypes table, I will have to make sure to create a check for that new type too.

  • Using COALESCE to avoid dynamic SQL ?

    - by krul
    I would like to use following sql to avoid constructing sql dynamically: SELECT CommentID, Comment, FROM Comments --if Author id is not null then filter upon author id otherwise get all comments (ignore author id) WHERE AuthorID LIKE COALESCE(@AuthorId, '%') --if comment type is present filter upon it, otherwise get all comments (ignore comment type condition) AND CommentType LIKE COALESCE(@CommentType, '%') I want to know is that safe way to approach this problem? EDIT: Here is final code that satisfy my need to ignore search parameter if is null and applied it if is present: SELECT CommentID, Comment, FROM Comments --if @AuthorId is not null then filter upon @AuthorId otherwise get all comments (ignore author id) WHERE AuthorID = COALESCE(@AuthorId, AuthorID) --if @CommentType is present filter upon it, otherwise get all comments (ignore comment type condition) AND CommentType = COALESCE(@CommentType, CommentType)

  • jquery get last ID of dynamic div

    - by Pjack
    Couldn't find an answer, but Im trying to get the last ID of the last div that was created on the page. The code I'm using doesn't seem to work using .last(). My syntax is probably wrong but I can't get it to show the ID. jQuery(document).ready(function() {jQuery("a.more_posts").live('click', function(event){ jQuery("div[id^='statuscontainer_']").last(); var id = parseInt(this.id.replace("statuscontainer_", "")); alert(id); }); });

  • Dynamic data validation in ASP.NET MVC

    - by user252160
    I've recently read about the model validation capabilities of ASP.NET MVC which are all very cool until a certain point. What happens if the application doesn't know the data that it works with because it is all stored in DB and built together at runtime. Just like in Drupal, I'd like to be able to define custom types at runtime, and assign runtime validation rules as well. Obviously, the idea of assigning attributes to well established models is now gone. What else could be done ? I am thinking in terms of rules being stored as JSON objects in the DB fields or something like that.

  • Using Hibernate with Dynamic Eclipse Plug-ins

    - by AlbertoPL
    I have classes that are named exactly the same across different plug-ins that I use for my application, and I'd like to be able to configure them properly with Hibernate. The problem is that it looks like Hibernate dynamically generates a class' package name when trying to find a class when it's doing its mapping. With one plug-in this scheme works, but across multiple plug-ins it's not working. It looks like Hibernate gets confused when dealing with Hibernate configuration files across multiple plug-ins. Is this because each plug-in has its own class-loader? What is the best way to proceed to make this work with the existing plug-ins and Hibernate?

  • "Dynamic" CSS styling in asp .net?

    - by DeeMac
    I have the following inside a content place holder in my asp .net pages: <style type="text/css"> #sortable1 { list-style-type: none; margin: 0; padding: 0; zoom: 1; } #sortable1 li { margin: 3px; padding: 3px; width: 90%; border: 1px solid #000000; background: #000000; color: #FFFFFF; } #sortable1 li.highlightWorkflow { background: #FFFF00; color: #000000; } </style> I would ideally like to swap the #00000's for values held on the page, maybe in hidden fields. Is this possible?

  • How do I create a dynamic data transfer object dynamically from ADO.net model

    - by Richard
    I have a pretty simple database with 5 tables, PK's and relationships setup, etc. I also have an ASP.net MVC3 project I'm using to create simple web services to feed JSON/XML to a mobile app using post/get. To access my data I'm using an ADO.net entity model class to handle generation of the entities, etc. Due to issues with serialization/circular references created by the auto-generated relations from ADO.net entity model, I've been forced to create "Data transfer objects" to strip out the relations and data that doesn't need to be transferred. Question 1: is there an easier way to create DTOs using the entity framework itself? IE, specify only the entity properties I want to convert to Jsonresults? I don't wish to use any 3rd party frameworks if I can help it. Question 2: A side question for Entity Framework, say I create an ADO.net entity model in one project within a solution. Because that model relies on the connection to the database specified in project A, can project B somehow use that model with a similar connection? Both projects are in the same solution. Thanks!

  • Complicated football league Dynamic Ordering in MySQL?

    - by Dan
    I have a table 'games' for a football league as follows: date home_team_id away_team_id home_score away_score - 1 2 6 21 - 3 1 7 19 I can't figure out how to dynamically generate a list of team ID's ordered by Wins (then points for if poss)? -- I have this query which works fine when I have a $team_id but of cause then I can only do 1 team at a time, and that doesn't allow for ordering at query level ((SELECT COUNT(*) FROM `games` WHERE ((`home_score` > `away_score`) AND `home_team_id` = '.$team_id.')) + (SELECT COUNT(*) FROM `games` WHERE ((`home_score` < `away_score`) AND `away_team_id` = '.$team_id.'))) AS `wins` I wonder if i can use this with some form of GROUP, or mySQL can know the $team_id itself? I've also tried some multiple JOINs with the 'team' table but they didn't work either. Thanks, Dan

  • How to pass dynamic parameters to .pde file

    - by Kalpana
    class Shape contains two methods drawCircle() and drawTriangle(). Each function takes different set of arguments. At present, I invoke this by calling the pde file directly. How to pass these arguments from a HTML file directly if I have to control the arguments being passed to the draw function? 1) Example.html has (current version) <script src="processing-1.0.0.min.js"></script> <canvas data-processing-sources="example.pde"></canvas> 2) Example.pde has class Shape { void drawCircle(intx, int y, int radius) { ellipse(x, y, radius, radius); } void drawTriangle(int x1, int y1, int x2, int y2, int x3, int y3) { rect(x1, y1, x2, y2, x3, y3); } } Shape shape = new Shape(); shape.drawCircle(10, 40, 70); I am looking to do something like this in my HTML file, so that I can move all the functions into a separate file and call them with different arguments to draw different shapes (much similar to how you would do it in Java) A.html <script> Shape shape = new Shape(); shape.drawCircle(10, 10, 3); </script> B.html <script> Shape shape = new Shape(); shape.drawTriangle(30, 75, 58, 20, 86, 75); </script> 2) Iam using Example2.pde has void setup() { size(200,200); background(125); fill(255); } void rectangle(int x1, int y1, int x2, int y2) { rect(x1, y1, x2, y2); } My Example2.html has var processingInstance; processingInstance.rectangle(30, 20, 55, 55); but this is not working.
