  • Creating a nested model form

    - by Elliot
    Hey Guys, I'm trying to build a multi model form - but one of the issues, is I need to link the models within the form. For example, lets say the form I have has the following models: Users, Profiles When creating a new user, I'd like to create a new profile simultaneously, and then link the two. The issue is, if neither have been created yet, they don't have ID's yet - so how can I assign linking values? Thanks! -Elliot

  • Codeigniter Best Practices for Model functions

    - by user270797
    Say my application has a "Posts" model, and one of the function is add_post(), it might be something like: function add_post($data) { $this-db-insert('posts',$data); } Where $data is an array: $data = array ('datetime'='2010-10-10 01:11:11', 'title'='test','body'='testing'); Is this best practice? It means if you use that function you need to know the names of the database fields where as my understanding of OOP is that you shouldnt need to know how the method works etc etc

  • Accordion - Expand/Collapse - but first panel is opened and screws it up

    - by lorenzium
    Hey guys, I've got an accordion which has the first panel opened on default by throwing in: $("h4#open").trigger('click'); (which triggers the first panel to act as if the h4 link were clicked, and thus opened...) But this seems to screw up the only way I can think of expanding / collapsing all the panels. I have this code to expand / collapse: $("a.ex-col").click(function(){ $("div.accordion div").slideToggle("slow"); return false; }); When using this, all the panels toggle open and close except any panel that happens to be open (or closed) at the time. How can I keep the default div opened on load, while also expanding / collapsing with the rest of them? Thanks.

  • Odd ActiveRecord model dynamic initialization bug in production

    - by qfinder
    I've got an ActiveRecord (2.3.5) model that occasionally exhibits incorrect behavior that appears to be related to a problem in its dynamic initialization. Here's the code: class Widget < ActiveRecord::Base extend ActiveSupport::Memoizable serialize :settings VALID_SETTINGS = %w(show_on_sale show_upcoming show_current show_past) VALID_SETTINGS.each do |setting| class_eval %{ def #{setting}=(val); self.settings[:#{setting}] = (val == "1"); end def #{setting}; self.settings[:#{setting}]; end } end def initialize_settings self.settings ||= { :show_on_sale => true, :show_upcoming => true } end after_initialize :initialize_settings # All the other stuff the model does end The idea was to use a single record field (settings) to persist a bunch of configuration data for this object, but allow all the settings to seamlessly work with form helpers and the like. (Why this approach makes sense here is a little out of scope, but let's assume that it does.) Net-net, Widget should end up with instance methods (eg #show_on_sale= #show_on_sale) for all the entires in the VALID_SETTINGS array. Any default values should be specified in initialize_settings. And indeed this works, mostly. In dev and staging, no problems at all. But in production, the app sometimes ends up in a state where a) any writes to the dynamically generated setters fail and b) none of the default values appear to be set - although my leading theory is that the dynamically generated reader methods are just broken. The code, db, and environment is otherwise identical between the three. A typical error message / backtrace on the fail looks like: IndexError: index 141145 out of string (eval):2:in []=' (eval):2:inshow_on_sale=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:in send' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:in each' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2634:in `update_attributes!' ...(then controller and all the way down) Ideas or theories as to what might be going on? My leading theory is that something is going wrong in instance initialization wherein the class instance variable settings is ending up as a string rather than a hash. This explains both the above setter failure (:show_on_sale is being used to index into the string) and the fact that getters don't work (an out of bounds [] call on a string just returns nil). But then how and why might settings occasionally end up as a string rather than hash?

  • Java JList model

    - by Alaa
    How can I make a list model from a JList in order to be able to insert an item into it. I want to use this method: addElement(java.lang.Object item) I found an explanation here, but the problem is that ListModel is an interface and even if I write an implementation and override its method, I can't use the addElement() method

  • Reporting Services 2005 Model using WCF Service for data

    - by Stu
    I am trying to use WCF Services as models for SQL Server Reporting Services 2005 reports. I can do this if I design the reports in the designer but cannot do it for a Reporting Model project which I think I need to make reports in the Report Builder. My full requirement is to have a report builder that the users can use building reports based on DTOs supplied from my WCF service. Thanks

  • How ca I return a value from a function

    - by Shadi Al Mahallawy
    I used a function to calculate information about certain instructions I intialized in a map,like this void get_objectcode(char*&token1,const int &y) { map<string,int> operations; operations["ADD"] = 18; operations["AND"] = 40; operations["COMP"] = 28; operations["DIV"] = 24; operations["J"] = 0X3c; operations["JEQ"] =30; operations["JGT"] =34; operations["JLT"] =38; operations["JSUB"] =48; operations["LDA"] =00; operations["LDCH"] =50; operations["LDL"] =55; operations["LDX"] =04; operations["MUL"] =20; operations["OR"] =44; operations["RD"] =0xd8; operations["RSUB"] =0x4c; operations["STA"] =0x0c; operations["STCH"] =54; operations["STL"] =14; operations["STSW"] =0xe8; operations["STX"] =10; operations["SUB"] =0x1c; operations["TD"] =0xe0; operations["TIX"] =0x2c; operations["WD"] =0xdc; if ((operations.find("ADD")->first==token1)||(operations.find("AND")->first==token1)||(operations.find("COMP")->first==token1) ||(operations.find("DIV")->first==token1)||(operations.find("J")->first==token1)||(operations.find("JEQ")->first==token1) ||(operations.find("JGT")->first==token1)||(operations.find("JLT")->first==token1)||(operations.find("JSUB")->first==token1) ||(operations.find("LDA")->first==token1)||(operations.find("LDCH")->first==token1)||(operations.find("LDL")->first==token1) ||(operations.find("LDX")->first==token1)||(operations.find("MUL")->first==token1)||(operations.find("OR")->first==token1) ||(operations.find("RD")->first==token1)||(operations.find("RSUB")->first==token1)||(operations.find("STA")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STL")->first==token1) ||(operations.find("STSW")->first==token1)||(operations.find("STX")->first==token1)||(operations.find("SUB")->first==token1) ||(operations.find("TD")->first==token1)||(operations.find("TIX")->first==token1)||(operations.find("WD")->first==token1)) { int y=operations.find(token1)->second; //cout<<hex<<y<<endl; } return ; } which if I cout y in the function gives me an answer just fine which is what i need but there is a problem tring to return the value from the function so that I could use it outside the function , it gives a whole different answer, what is the problem

  • sed to insert on first match only

    - by SS.
    UPDATED: Using sed, how can I insert (NOT SUBSTITUTE) a new line on only the first match of keyword for each file. Currently I have the following but this inserts for every line containing Matched Keyword and I want it to only insert the New Inserted Line for only the first match found in the file: sed -ie '/Matched Keyword/ i\New Inserted Line' *.* For example: Myfile.txt: Line 1 Line 2 Line 3 This line contains the Matched Keyword and other stuff Line 4 This line contains the Matched Keyword and other stuff Line 6 changed to: Line 1 Line 2 Line 3 New Inserted Line This line contains the Matched Keyword and other stuff Line 4 This line contains the Matched Keyword and other stuff Line 6

  • Model Validation for record creation in rails

    - by Elliot
    Hey Guys, Lets say the model for books is: created_at user_id (int) author_id (int) genre_id (int) pages (int) I want to let people change the "created_at" field upon record creation. I also want to make sure that a record can't have the exact same created_at, user_id, and author_id as any other record (i.e. each needs its own date). Whats the best to perform this type of validation, and how should I go about doing it? Best, Elliot

  • Detecting first time login of user into application (Google Appengine)

    - by Jake
    My app requires users to login using their google account. I have this set in my App.yamp file: url: /user/.* script: user.py login: required Now when any user tries to access files under /user/secret.py he will need to authenticate via google, which will redirect the user back to /user/secret.py after successful authentication. Now the problem I am facing is when the user is redirected back to the app, I cannot be sure if this is the first time the user has logged in or is it a regular user to my site who has come back again from just the user object which google passes using users.get_current_user() . I thus need to maintain state in the datastore to check if the user already exists or not everytime. If he does not exist i need to create a new entry with other application specific settings. My question is: Is there some easier way to handle this? without having to query the datastore to figure if this is a first time user or a regular one?

  • How to monkeypatch Issue model in Redmine from a plugin, specifically redmine_task_board

    - by armmer
    I'm trying to add a custom sort method to the Issue.rb model in Redmine from the redmine_task_board plugin. My commit on github I don't know if this is a lack of knowledge about Rails plugins on my part or something specific I have to do with Redmine. Redmine 0.8.6.stable I want this method so that when I show the Task Board show method from tasks_board_controller I can sort the tickets in each column by Issue.priority.position. Thank you for any help.

  • Bulk Insert takes 4x as long on first operation of the day

    - by patrick
    I do Bulk Inserts into a table with about 14 million rows at fiver minute increments during a 7 hour period during the day. These inserts take somewhere between 9-14 secs. However, the first insert always takes about 40 secs. Anyone know what SQL Server 2005 would be doing differently on the first insert into a table for that day? From what I've read I should probably use the SqlBulkCopy class instead of just using a bulk insert in a stored procedure. Is that that the general consensus?

  • What situations does a Monostate pattern model?

    - by devoured elysium
    I know what both a Singleton or a Monostate are and how to implement them. Although I can see many uses for a Singleton, I can't imagine a situation where I would want to let the user create as many instances of my class although in reality only one really exists behind the scenes. Can anybody help me here? I know that for several reasons one should stay away from both patterns, but in theory, what kind of problems does the Monostate model? Thanks

  • Fast iterating over first n items of an iterable in python

    - by martinthenext
    Hello! I'm looking for a pythonic way of iterating over first n items of a list, and it's quite important to do this as fast as possible. This is how I do it now: count = 0 for item in iterable: do_somethin(item) count += 1 if count >= n: break Doesn't seem neat to me. Another way of doing this is: for item in itertools.islice(iterable, n): do_something(item) This looks good, the question is it fast enough to use with some generator(s)? For example: pair_generator = lambda iterable: itertools.izip(*[iter(iterable)]*2) for item in itertools.islice(pair_generator(iterable), n): so_something(item) Will it run fast enough as compared to the first method? Is there some easier way to do it?

  • Save simple data in Magento's DB w/o Model

    - by Joseph Mastey
    I'm looking to save some data in the Magento database without hassling with creating a new EAV object (or even a DB table if I can avoid it). Is there any place that you all know about that Magento will let you store serialized data? If it matters, the data is a serialized set of SKUs that I need to retrieve. I know that I could create a new model, or possibly even create an attribute as a flag on each product, but those are both really overkill for my purposes. Thanks, Joe

  • List of Django model instance foreign keys losing consistency during state changes.

    - by Joshua
    I have model, Match, with two foreign keys: class Match(model.Model): winner = models.ForeignKey(Player) loser = models.ForeignKey(Player) When I loop over Match I find that each model instance uses a unique object for the foreign key. This ends up biting me because it introduces inconsistency, here is an example: >>> def print_elo(match_list): ... for match in match_list: ... print match.winner.id, match.winner.elo ... print match.loser.id, match.loser.elo ... >>> print_elo(teacher_match_list) 4 1192.0000000000 2 1192.0000000000 5 1208.0000000000 2 1192.0000000000 5 1208.0000000000 4 1192.0000000000 >>> teacher_match_list[0].winner.elo = 3000 >>> print_elo(teacher_match_list) 4 3000 # Object 4 2 1192.0000000000 5 1208.0000000000 2 1192.0000000000 5 1208.0000000000 4 1192.0000000000 # Object 4 >>> I solved this problem like so: def unify_refrences(match_list): """Makes each unique refrence to a model instance non-unique. In cases where multiple model instances are being used django creates a new object for each model instance, even if it that means creating the same instance twice. If one of these objects has its state changed any other object refrencing the same model instance will not be updated. This method ensure that state changes are seen. It makes sure that variables which hold objects pointing to the same model all hold the same object. Visually this means that a list of [var1, var2] whose internals look like so: var1 --> object1 --> model1 var2 --> object2 --> model1 Will result in the internals being changed so that: var1 --> object1 --> model1 var2 ------^ """ match_dict = {} for match in match_list: try: match.winner = match_dict[match.winner.id] except KeyError: match_dict[match.winner.id] = match.winner try: match.loser = match_dict[match.loser.id] except KeyError: match_dict[match.loser.id] = match.loser My question: Is there a way to solve the problem more elegantly through the use of QuerySets without needing to call save at any point? If not, I'd like to make the solution more generic: how can you get a list of the foreign keys on a model instance or do you have a better generic solution to my problem? Please correct me if you think I don't understand why this is happening.

  • WPF/MVVM: Delegating a domain Model collection to a ViewModel

    - by msfanboy
    A domain model collection (normally a List or IEnumerable) is delegated to a ViewModel. Thats means my CustomerViewModel has a order collection of type List or IEnumerable. No change in the list is recognized by the bound control. But with ObservableCollection it is. This is a problem in the MVVM design pattern. How do you cope with it?

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

  • Fast iterating over first n items of an iterable (not a list) in python
