  • rails: has_many :through + polymorphism validation?

    - by ramonrails
    I am trying to achieve this. Any hints? A project has many users through join model A user has many projects through join model Admin class inherits User class. It also has some Admin specific stuff. Admin like inheritance for Supervisor and Operator Project has one Admin, One supervisor and many operators. Now I want to 1. submit data for project, admin, supervisor and operator in a single project form 2. validate all and show errors on the project form. Project has_many :users, :through = :projects_users User has_many :projects, :through = :projects_users ProjectsUser = :id integer, :user_id :integer, :project_id :integer, :user_type :string ProjectUser belongs_to :project, belongs_to :user, :polymorphic = true Admin < User Supervisor < User Operator < User Is the approach correct?

  • Getting search results from Twitter in php

    - by Mark Mayo
    I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

  • looking for a javascript engine

    - by c0f33.alex
    i'm looking for a js engine to that I can (easily) expose C/C++ functions, classes etc. The API should allow changing exposed values from within C++ (by storing some kind of pointer or reference to an object inside js or so...). I've considered using google's v8 but I'm new to it and don't know whether it will satisfy my requirements. Can someone tell me whether I should stick to v8 or try something else?

    In the example below I am wanting to do all of the 'safety' checks on the $_POST variables but it seems when I click submit I get a white page why?

  • Master data validation in service layer

    - by rakesh-nitj
    User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

  • How can I ensure that JavaScript inserted via AJAX will be executed after the accompanying HTML (als

    - by RenderIn
    I've got portions of pages being replaced with HTML retrieved via AJAX calls. Some of the HTML coming back has JavaScript that needs to be run once in order to initialize the accompanying HTML (setting up event handlers). Since the document has already been loaded, when I replace chunks of HTML using jQuery's .html function, having jQuery(document).ready(function() {...}); doesn't execute since the page loaded long before and this is just a snippet of HTML being replaced. What's the best way to attach event handlers whose code is packaged along with the HTML it's interested in, when that content is loaded via AJAX? Should I just put a procedural block of javascript after the HTML , so that when I insert the new HTML block, jQuery will execute the javascript immediately? Is the HTML definitely in the DOM and ready to be acted upon by JavaScript which is in the same .html call?

  • C# array of objects - conditional validation

    - by fishdump
    Sorry about the vague title! I have an class with a number of member variables (system, zone, site, ...) public sealed class Cello { public String Company; public String Zone; public String System; public String Site; public String Facility; public String Process; //... } I have an array of objects of this class. private Cello[] m_cellos = null; // ... I need to know whether the array contains objects with the same site but different systems, zones or companies since such a situation would be illegal. I have various other checks to make but they are all along similar lines. The Array class has a number of functions that look promising but I am not very up on defining 'key selector' functions and things like that. Any suggestions or pointers would be greatly appreciated. --- Alistair.

  • url validation in ruby on rails

    - by jpallavi
    1)Url field should also accept url as “www.abc.com”. If user enters url like this, it should be automatically appended with “http://” resulting in value saved in database as “http://www.abc.com”. If user enters url as “http://www.xyz.com” system should not append “http://”. User should be able to save url with “https://”. what is the code for it in ruby on rails?

  • java phone number validation....

    - by user69514
    Here is my problem: Create a constructor for a telephone number given a string in the form xxx-xxx-xxxx or xxx-xxxx for a local number. Throw an exception if the format is not valid. So I was thinking to validate it using a regular expression, but I don't know if I'm doing it correctly. Also what kind of exception would I have to throw? Do I need to create my own exception? public TelephoneNumber(String aString){ if(isPhoneNumberValid(aString)==true){ StringTokenizer tokens = new StringTokenizer("-"); if(tokens.countTokens()==3){ areaCode = Integer.parseInt(tokens.nextToken()); exchangeCode = Integer.parseInt(tokens.nextToken()); number = Integer.parseInt(tokens.nextToken()); } else if(tokens.countTokens()==2){ exchangeCode = Integer.parseInt(tokens.nextToken()); number = Integer.parseInt(tokens.nextToken()); } else{ //throw an excemption here } } } public static boolean isPhoneNumberValid(String phoneNumber){ boolean isValid = false; //Initialize reg ex for phone number. String expression = "(\\d{3})(\\[-])(\\d{4})$"; CharSequence inputStr = phoneNumber; Pattern pattern = Pattern.compile(expression); Matcher matcher = pattern.matcher(inputStr); if(matcher.matches()){ isValid = true; } return isValid; } Hi sorry, yes this is homework. For this assignments the only valid format are xxx-xxx-xxxx and xxx-xxxx, all other formats (xxx)xxx-xxxx or xxxxxxxxxx are invalid in this case. I would like to know if my regular expression is correct

  • How to store and access JSON data for a site?

    - by Callmeed
    I'm buiding an HTML/jQuery site where almost all the content comes from remote JSON data. I'm having trouble coming up with a good way to store and access the data in the future (scope-wise). Currently, I've written a jQuery plugin that gets the JSONP data when the site loads. But I have other functions and jQuery plugins that need to access this data. Where should this data be stored so other functions and plugins can access it? Should it be a global variable? If it matters, this site will only run on the iPad and the back-end of the site is in Rails.

  • Validate dependent model validation and show error message.

    - by piemesons
    Just taking a simple example. We have a question on stackoverflow and while posting a question we want to validate title_of_question, description_of_question that they should be present. Now we have a another model tag having habtm relationshio with question model. How to validate that while saving the question. Means question must have some tags. here the code:-- Models:-- class Question < ActiveRecord::Base belongs_to :user has_and_belongs_to_many :tags has_many :comments, :as => :commentable has_many :answers, :dependent => :destroy validates_presence_of :title, :content, :user_id end class Tag < ActiveRecord::Base has_and_belongs_to_many :questions validates_presence_of :tag end Form for entering question and tag <div class="form"> <% form_for :question ,@question, :url => {:action => "create" } do |f| %> <fieldset> <%= f.error_messages %> <legend>Post a question</legend> <div> <%= f.label :title %>: <%= f.text_field :title, :size => 100 %> </div> <div> <%= f.label :content ,'Question' %>: <%= f.text_area :content, :rows => 10, :cols => 100 %> </div> <div> <%= label_tag 'tags' %>: <%= text_field_tag 'tag' ,'',:size=> 60 %> add multiple tag using comma </div> <div> <%= submit_tag "Post question" %> </div> </fieldset> <% end %> </div> From Controller.. (Right now question will be saved without validating tag) def create @question = Question.new(params[:question]) @question.user_id=session[:user_id] if @question.save flash[:notice] = "Question has been posted." redirect_to question_index_path else render :action => "new" end end questions_tags table has been created. One approach is creating a virtual column using attribute accessors. another approach is validate associated. right now assuming new tags can be created.(but not duplicate).
