  • Grails - Need to restrict fetched rows based on condition on join table

    - by sector7
    Hi guys, I have these two domains Car and Driver which have many-to-many relationship. This association is defined in table tblCarsDrivers which has, not surprisingly, primary keys of both the tables BUT additionally also has a new boolean field deleted. Herein lies the problem. When I find/get query on domain Car, I am fetched all related drivers irrespective of their deleted status in tblCarsDrivers, which is expected. I need to put a clause/constraint to exclude the deleted drivers from the list of fetched records. PS: I tried using an association domain CarDriver in joinTable name but that seems not to work. Apparently it expects only table names, not maps. PPS: I know its unnatural to have any other fields besides the mapping keys in mapping table but this is how I got it and it cant be changed. Car domain is defined as such - class Car { Integer id String name static hasMany = [drivers:Driver] static mapping = { table 'tblCars' version false drivers joinTable:[name: 'tblCarsDrivers',column:'driverid',key:'carid'] } } Thanks!

  • MySQL::Eliminating redundant elements from a table?

    - by Legend
    I have a table like this: +-------+---------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+---------+------+-----+---------+-------+ | v1 | int(11) | YES | MUL | NULL | | | v2 | int(11) | YES | MUL | NULL | | +-------+---------+------+-----+---------+-------+ There is a tremendous amount of duplication in this table. For instance, elements like the following: +------+------+ | v1 | v2 | +------+------+ | 1 | 2 | | 1 | 3 | | 1 | 4 | | 1 | 5 | | 1 | 6 | | 1 | 7 | | 1 | 8 | | 1 | 9 | | 2 | 1 | | 4 | 1 | | 5 | 1 | | 6 | 1 | | 7 | 1 | | 8 | 1 | | 9 | 1 | +------+------+ The table is large with 1540000 entries. To remove the redundant entries (i.e. to get a table having only (1,9) and no (9,1) entries), I was thinking of doing it with a subquery but is there a better way of doing this?

  • Cakephp: Extend search capability to hasMany Relationship

    - by Chris
    I have two models: Car hasMany Passengers Passenger belongsTo Car I want to implement a search using Cake Search. The user should input a number and the searchengine should return all cars that have less than this number passengers. In my search form: echo $form->input('passengers', array('label' => 'Passengers', 'div' => false)); In my Car model: public $filterArgs = array( array('name' => 'passengers', 'type' => 'int'), ); In the controller: public $presetVars = array( array('field' => 'passengers', 'type' => 'int') } I thought of adding a function to the model that returns the number of passengers: function countPassengers(){ return(count($this->Car->Passenger)); //Not sure if this works } And how to I implement this search criteria?: return all Cars where countPassengers()<passenger

  • Django: Data corrupted after loading? (possible programmer error)

    - by Rosarch
    I may be loading data the wrong way. excerpt of data.json: { "pk": "1", "model": "myapp.Course", "fields": { "name": "Introduction to Web Design", "requiredFor": [9], "offeringSchool": 1, "pre_reqs": [], "offeredIn": [1, 5, 9] } }, I run python manage.py loaddata -v2 data: Installed 36 object(s) from 1 fixture(s) Then, I go to check the above object using the Django shell: >>> info = Course.objects.filter(id=1) >>> info.get().pre_reqs.all() [<Course: Intermediate Web Programming>] # WRONG! There should be no pre-reqs >>> from django.core import serializers >>> serializers.serialize("json", info) '[{"pk": 1, "model": "Apollo.course", "fields": {"pre_reqs": [11], "offeredIn": [1, 5, 9], "offeringSchool": 1, "name": "Introduction to Web Design", "requiredFor": [9]}}]' The serialized output of the model is not the same as the input that was given to loaddata. The output has a non-empty pre_req list, whereas the input's pre_reqs field is empty. What am I doing wrong?

  • Is it safe to validate a URL with a regexp?

    - by Vilx-
    In my web app I've got a form field where the user can enter an URL. I'm already doing some preliminary client-side validation and I was wondering if I could use a regexp to validate if the entered string is a valid URL. So, two questions: Is it safe to do this with a regexp? A URL is a complex beast, and just like you shouldn't use a regexp for parsing HTML, I'm worried that it might be unsuitable for a URL as well. If it can be done, what would be a good regexp for the task? (I know that Google turns up countless regexps, but I'm worried about their quality). My goal is to prevent a situation where the URL appears in the web page and is unusable by the browser.

  • Is this query safe in SQL Server?

    - by xaw
    I have this SQL update query: UPDATE table1 SET table1.field1 = 1 WHERE table1.id NOT IN (SELECT table2.table1id FROM table2); Other portions of the application can add records to table2 which use the field table1id to reference table1. The goal here is to remove records from table1 which aren't referenced by table2. Does SQL Server automatically lock table2 with this kind of query so that a new record can't be added to table2 while executing this query? I've also considered: UPDATE table1 SET field1 = 1 WHERE 0 = (SELECT COUNT(*) FROM table2 WHERE table1.id = table2.table1id); Which seems possibly safer, but much slower (because a SELECT would be called on each row of table1 instead of just one select for the NOT IN)

  • In C, is it possible do free only an array first or last position?

    - by user354959
    Hi there! I've an array, but I don't need its first (or last) position. So I point a new variable to the rest of the array, but I should free the array first/last position. For instance: p = read_csv_file(); q = p + 1; // I don't need the first CSV file field // Here I'd like to free only the first position of p return q; Otherwise I've to memcpy the array to other variable, excluding the first position, and then free the original array. Like this: p = read_csv_file(); q = (int*) malloc(sizeof(int) * (SOME_SIZE - 1)); memcpy(q, p+1, sizeof(int) * (SOME_SIZE - 1)); free(p); return q; But then I'll have the overhead of copying all the array. Is this possible to only free a single position of an array?

    - by denisioru
    Hello, I have MSSQL 2008 Ent and OLTP database with two big tables. How I can move this tables to another filegroup without service interrupting?

I looking for solution via google, but all solutions contain "create second table, insert rows from first table, drop first table, bla bla bla". Can I use partitioning functions for solving this problem? Thank you.

  • MySQL update error when special characters are used

    - by Katy
    Hi All, I was wondering if anyone had come across this one before. I have a customer who uses special characters in their product description field. Updating to a MySQL database works fine if we use their HTML equivalents but it fails if the character itself is used (copied from either character map or Word I would assume). Has anyone seen this behaviour before? The character in question in this case is ø - and we can't seem to do a replace on it (in ASP at least) as the character comes though to the SQL string as a "?". Any suggestions much appreciated - thanks!

    The code below works as expected in FF but not in IEs... $(document).ready(function() { $('div.facet_dropdown select').live('change', function() { var changed_facet = $(this).attr('id'); var facets = $('select', $(this).closest('form')); var args = window.location.href.split('?')[0] + '?ajax=1'; var clear = false; for(var i = 0; i < facets.length; i++) { var ob = $(facets[i]); var val = ob.val(); if(clear) { val = ''; } args += '&' + ob.attr('id') + '=' + val; if(ob.attr('id') == changed_facet) { clear = true; } } $.getJSON(args, function(json) { for(widget_id in json) { var sel = '#field-' + widget_id + ' div.widget'; $(sel).html(json[widget_id]); } }); }); });

  • Change the value of a dropdown if it is equal to something

    - by Jake Neal
    Sorry if this question has already been asked and answered, but I couldn't find anything specifically for my needs. I have a form that has placeholders and javascript to make sure the form isn't submitted with the placeholders still there. There is a dropdown box that has the value of 'Best time to call'. What I want to do is if this value is passed as the default, I want it to change to something like "n/a" or a blank value. I have achieved this with the comments box using the following javascript, but it doesn't seem to work the same for the dropdown: var comments=document.getElementById('comments').value; if (comments=="Comments") { document.getElementById('comments').value=""; } This isn't a required field so I can't have an alert come up, so I just need to value to be changed if submitted as 'Best time to call'. Hope I have explained everything correctly

  • Conditional value for ActiveRecord create method only

    - by Steve Wright
    I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

  • Tools for viewing logs of unlimited size

    - by jkff
    It's no secret that application logs can go well beyond the limits of naive log viewers, and the desired viewer functionality (say, filtering the log based on a condition, or highlighting particular message types, or splitting it into sublogs based on a field value, or merging several logs based on a time axis, or bookmarking etc.) is beyond the abilities of large-file text viewers. I wonder: Whether decent specialized applications exist (I haven't found any) What functionality might one expect from such an application? (I'm asking because my student is writing such an application, and the functionality above has already been implemented to a certain extent of usability)

  • Why isn't the copy constructor elided here?

    - by Jesse Beder
    (I'm using gcc with -O2.) This seems like a straightforward opportunity to elide the copy constructor, since there are no side-effects to accessing the value of a field in a bar's copy of a foo; but the copy constructor is called, since I get the output meep meep!. #include <iostream> struct foo { foo(): a(5) { } foo(const foo& f): a(f.a) { std::cout << "meep meep!\n"; } int a; }; struct bar { foo F() const { return f; } foo f; }; int main() { bar b; int a = b.F().a; return 0; }

  • Is shortening properties names worth it?

    - by raam86
    in how to node Blog rolling with node.js and mongoDB the author mentions it's a good idea to shorten proprieties names: ....oft-reported issue with mongoDB is the size of the data on the disk... each and every record stores all the field-names .... This means that it can often be more space-efficient to have properties such as 't', or 'b' rather than 'title' or 'body', however for fear of confusion I would avoid this unless truly required! I am aware of solutions of how to do it I am more intrested in when is it truly required?

  • CDateTimeCtrl - preventing 'focus' change when setting date

    - by WalderFrey
    I'd like to use a CDateTimeCtrl to allow the user to select a non-weekend date. So, if the user increments the day (via a keypress) - and the resulting day is found to fall on a weekend - then the control should skip forward to the following Monday (don't let issues about month changes distract you, it's not relevant). Usually it's not a problem: when I handle the DTN_DATETIMECHANGE notification I can check the new date/time and if it's found to be a weekend then I can call SetTime on the control to update the date. However, if I set the style to DTS_SHOWNONE, this call to SetTime causes the control to shift the input 'focus' (term used loosely) to the 'none' checkbox, e.g. away from the day field. This prevents the user from using keyboard input to continue incrementing the date unless they subsequently use the right arrow key to reset the 'focus', which is just nasty. I would dearly like to prevent this focus shift from occurring. Is it even possible?

  • Arguments against Create or Update

    - by Nix
    Recently someone stated that they thought all Creates should be CreateOrUpdates. Instinctively i thought bad, but now I am trying to find out if I have any grounds. Situation interface IService{ void Create(Object a); void Update(Object a); } or interface IService{ void CreateOrUpdate(Object a); } My first thought is if you implemented everything CreateOrUpdate then you have no control if someone accidentally sends you wrong data, or concurrency issues where someone changes a "primary" field right before you call update.... But if you remove those cases, are there any other cons?

  • Dismissing the keyboard in a UIScrollView

    - by Nicholas1024
    Alright, I have a couple of UITextFields and UITextViews inside a UIScrollView, and I'd like to set the keyboard to disappear whenever the scrollview is touched or scrolled (except when you touch down inside the text field/view, of course). My current attempt at doing this is replacing the UIScrollView with a subclass, and setting it to call a removeKeyboard function (defined inside the main view controller) inside the touchesBegan method. However, this only removes the keyboard for a normal touch, not when the view is simply scrolled. So, what's the best way to remove the keyboard inside a UIScrollView? Thanks in advance for your help.

  • jQuery focus on content of input / textarea - not working properly in IE8

    - by katebp
    I want the input fields on my site to select all the text when the user first clicks on them, but in IE8 the text is selected for a split second then reverts back to normal. Works fine in FF. My js code: $(document).ready(function () { //HTML DOM document is ready // Add this behavior to all text fields $("input[type='text'], textarea").live("focus", function(){ // Select field contents this.focus(); }); }); Any ideas? I've tried adding ".select()" after "this" and bizarrely enough it works, but throws loads of js errors in FF and IE. Thanks

  • Database normalization and duplicate values

    - by bretddog
    Consider a Parent / Child / GrandChild structure in a database table schema, or even a deeper hierarchy. These being in the same aggregate. One table DAYS keeps a single row per day, and has a "Date" field. This is the root table, or maybe a child of the root. No row can ever be deleted in this table. In this case, however complex my table schema looks like, however far away in the hierarchy any other table is, is there any reason why any other table would hold a Date value? Can't it instead just have a FK to the DAYS table. I obviously assume that the creation of these date fields happen not before such datefield exist in the DAYS table. I'm now thinking just about the date part to be relevant, not the time part. Not sure if all databases can store these individually. That's maybe relevant, but not really the focus of the question.
