  • Rails: validate presence of parent_id in has_many association

    - by deb
    I have a projects resource that has many tasks. I want to ensure that every task has a project_id by adding validates_presence_of :project_id to the tasks model. However, when creating a new project with tasks, the project_id won't be available until the record saves, therefore I can't use validates_presence_of :project_id. So my question is, how do I validate presence of project_id in the task model? I want to ensure every task has a parent. ... class Project < ActiveRecord::Base has_many :tasks, :dependent => :destroy accepts_nested_attributes_for :tasks, :allow_destroy => true ... class Task < ActiveRecord::Base belongs_to :project validates_presence_of :project_id

  • Rails - Searching multiple textboxes and fields

    - by ChrisWesAllen
    I have a model of events that has various information such as date, location, and description of whats going on. I would like for my users to be able to search through the events list through a set of different textboxes but I having a hard time getting the syntax just right in my view I have... <% form_tag users_path, :method => 'get' do %> (<%= text_field_tag :search_keyword, params[:search_keyword] %>) + (<%= text_field_tag :search_zip, params[:search_zip] %>) <%= submit_tag "Find Events!", :name => nil %> <% end %> and in the controller I'm trying to query through the results.... if params[:search_keyword] @events = Event.find(:all, :conditions => [' name LIKE ? ', "%#{params[:search_keyword]}%"]) elsif params[:search_zip] @events = Event.find(:all, :origin=> params[:search_zip], :within=>50 ) else @events = Event.find(:all) end How do I code it so that it will perform the search only if the textbox isnt empty? also if both textboxes are filled then @events should be the product of BOTH queries? if have no idea if this would work =(???@event = @event+ event.find.....???

  • defaults for to_json in Rails with :include

    - by prateekdayal
    Let us say I have a model Post which belongs to a User. To convert to json, I do something like this @reply.to_json(:include => {:user => {:only => [:email, :id]}, :only => [:title, :id]) However, I want to set some defaults for this so I don't have to specify :only everytime. I am trying to override as_json to accomplish this. When I add as_json in User model, it is called when I do @user.to_json but when user is included in @reply.to_json, my overriden as_json for User is ignored. How do I make this work? Thanks

    - by Newy

How do I set the tab to be custom. say I want second tab to be shown first. $('#tabs').tabs(2) does not work. i got that from this link Let say I click on a button inside tab1. Clicking on the button takes control back to an action and then control comes back to this page. When the control comes back...then is it possible to set a custom tab?. For example. in tab 1 I click something...go back to the action...and then I want to come back to tab 2.

  • rails route question

    - by badnaam
    I am trying to build a search functionality which at a high level works like this. 1 - I have a Search model, controller with a search_set action and search views/partial to render the search. 2 - At the home page a serach form is loaded with an empty search object or a search object initialized with session[:search] (which contains user search preferences, zip code, proximity, sort order, per page etc). This form has a post(:put) action to search_set. 3 - When a registered user performs a set the params of the search form are collected and a search record is saved against that user. If a unregistered user performs a search then the search set action simply stores the params in the session[:search]. In either case, the search is executed with the given params and the results are displayed. At this point the url of in the location bar is something like.. http://localhost:3000/searches/search_set?stype=1 At this point if the user simply hits enter on the location bar, I get an error that says "No action responded to show" I am guessing because the URL contains search_set which uses a put method and even though I have a search_show (:get) action (which simply reruns the search in the session or saved in the database) does not get called. How can I handle this situation where I can route a user hitting enter into the location bar to a get method? If this does not explain the problem , please let me know I can share more details/code etc. Thanks!

  • rails: Get a list of items tagged x AND y AND z

    - by egarcia
    I've got two models: item and tags. Both have a name attribute. I want to find items tagged with several tags. class Item < ActiveRecord::Base has_many :tags validates_presence_of :name end class Tag < ActiveRecord::Base belongs_to :item validates_presence_of :name end Given a list of tag ids, I can easily enough get the list of items tagged with one tag or the other: # Find the items tagged with one or more of the tags on tag_ids Item.all(:conditions => ['tags.id in (?)', tag_ids], :joins => :tags) If tag_ids is {1,4}, then I get all pictures tagged with 1, or 4, or both. I want to know now how to get the pictures that are tagged with both - 1 AND 4. I can't even imagine the SQL that is needed here.

    - by Martin Petrov
    Is it possible to render different actions based on what fails at validation? For example - I have one field in the form - email addres. It is validated like this: validates :email, :presence => true, :uniqueness => { :case_sensitive => false } In the controller: def create @user = User.new(params[:user]) if @user.save redirect_to somewhere else # render :new if email is blank # redirect_to somwhere if email is taken end end

  • Rendering HTML in rails without actually displaying it

    - by Kevin Whitaker
    Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

  • Help me with query string parameters (Rails)

    - by Martin Petrov
    Hi, I'm creating a newsletter. Each email contains a link for editing your subscription: <%= edit_user_url(@user, :secret => @user.created_at.to_i) %> :secret = @user.created_at.to_i prevents users from editing each others profiles. def edit @user = user.find(params[:id]) if params[:secret] == @user.created_at.to_i render 'edit' else redirect_to root_path end end It doesn't work - you're always redirected to root_path. It works if I modify it like this: def edit @user = user.find(params[:id]) if params[:secret] == "1293894219" ... 1293894219 is the "created_at.to_i" for a particular user. Do you have any ideas why?

  • Changing a select input to a checkbox acting as an on/off toggle switch in Rails

    - by Ribena
    I have a set of 7 dropdown inputs allowing admins to say whether they are open or closed for business on a given day. I'd like that changed to 7 open/closed switches (presumably styled checkboxes?) but can't figure out how to do this! Here are the relevant bits of code I currently have (prior to any change): app/view/backend/inventory_pool/edit.html.haml - content_for :title, @inventory_pool = form_for [:backend, @inventory_pool], html: {name: "form"} do |f| .content - if is_admin? %a.button{:href => root_path}= _("Cancel") %button.button{:type => :submit}= _("Save %s") % _("Inventory Pool") %section %h2= _("Basic Information") .inner .field.text .key %h3= "#{_("Print Contracts")}" %p.description .value .input %input{type: "checkbox", name: "inventory_pool[print_contracts]", checked: @inventory_pool.print_contracts} %section#workdays %h2= _("Workdays") .inner - [1,2,3,4,5,6,0].each do |i| .field.text .key %h3= "#{I18n.t('date.day_names')[i]}" .value .input %select{:name => "store[workday_attributes][workdays][]"} %option{:label => _("Open"), :value => Workday::WORKDAYS[i]}= _("Open") %option{:label => _("Closed"), :value => "", :selected => @store.workday.closed_days.include?(i) ? true : nil}= _("Closed") app/models/workday.rb class Workday < ActiveRecord::Base belongs_to :inventory_pool WORKDAYS = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"] def is_open_on?(date) return false if date.nil? case date.wday when 1 return monday when 2 return tuesday when 3 return wednesday when 4 return thursday when 5 return friday when 6 return saturday when 0 return sunday else return false #Should not be reached end end def closed_days days = [] days << 0 unless sunday days << 1 unless monday days << 2 unless tuesday days << 3 unless wednesday days << 4 unless thursday days << 5 unless friday days << 6 unless saturday days end def workdays=(wdays) WORKDAYS.each {|workday| write_attribute(workday, wdays.include?(workday) ? true : false)} end end And in app/controllers/backend/inventory_pools_controller I have this (abridged): def update @inventory_pool ||= InventoryPool.find(params[:id]) process_params params[:inventory_pool] end def process_params ip ip[:print_contracts] ||= "false" # unchecked checkboxes are *not* being sent ip[:workday_attributes][:workdays].delete "" if ip[:workday_attributes] end

  • rails: self-referential association

    - by john
    hi, My needs are very simple: I have a Tip table to receive comments and have comments to receive comments, too. To retrieve each comment that is stored in the same table (comments), I created another key for the comments on comments: "inverse_comments". I tried to use one comments table by using self-referntial association. Some resources seem to bring more than one table into the piture which are diffent from my needs. So I came up whth the following modeling for comments: class Comment < ActiveRecord::Base belongs_to :tip belongs_to :user has_many :mycomments, :through => :inverse_comments, :source => :comment end Apparently something is missing here but I cannot figure it out. Could some one enlighten me on this: what changes I need to do to make the model work? thanks.

  • Ruby on Rails - can't access datetime model object

    - by NomadicRiley
    I've created a model that has 3 string columns and a datetime. Everything is running in SQLite3 and I can view the records in my table just fine using Lita. I'm trying to display the values in a page (index action) using code like this: <% @details.each do |lifeCycle| % <%= debug(lifeCycle)% <%= lifeCycle.lifeCycleId % <%= lifeCycle.eventType % <%= debug(lifeCycle.timeId) % <% end % From the debug I get a result like this: --- !ruby/object:LifeCycle attributes: eventType: Order created_at: "2111359287.23037" timeId: "2455364.89983796" eventId: "98765" updated_at: "2111359287.23037" lifeCycleId: "12345" id: "1" attributes_cache: {} But whenever I try to access the event timeId - i' getting a nil value. This is true if i try to run debug on just that field debug(lifeCycle.timeId), or call a function on it. Is there something obvious I'm missing here?

  • Rails subscription limitations

    - by David Lyod
    I have an application with set limits on subscription attributes i/e a user can have five projects for subscription A but have ten for subscription B At present I run a check on there current usage when linking to the create action and if they are over there limit I do not display the link to create a new project. On the view (for the new project ) I again run the check (in a helper) to see if they can create a new project and if they are not I display a message stating so and a little upgrade link. Is this a secure method of stopping a user bypassing there subscription attribute limitations ? What about direct PUT requests etc ?

  • Block call in Ruby on Rails

    - by Mattias
    Hi, I'm trying to clean up my code and get rid of a lot of ugly hashes. In my views I define several actions like this: @actions = { :interest => {'Show interest', link_to(..), :disabled => true}, :follow => {'Follow this case', link_to(..)} ... } As these hashes grow, the maintainability decreases. I want to convert the above format to something like: actions do item :interest, 'Show interest', link_to(..), :disabled => true item :follow, 'Follow', link_to(..) ... end How do I structure my helper methods to allow this? Preferably the 'item'-method should only be available in the 'actions' block and not in the global scope. Thanks!
