In part of my application I''m using dynamic tables. I''m aware of the single thread conditions. I''ve tackled some caveats yet - will post a blog about it soon - but there''s one I need help with. Consider 2 models that are associated: Order and OrderLine where Order has many order_lines. Now we set the table names for them:

Hi, I''m having great fun developing with Rails but I''ve come to a problem that I can''t quite figure out. I have an Order object that "has_many" order_lines. This works perfectly and I can see all the lines. The OrderLine object has an order_id field as well as product_id and amount. Now ideally I would want to do : order.orderline[0].product.name for

Hi.. Guys new plugin again Foreign Key Associations is a plugin that automatically creates associations based on foreign-keys. The associations are created at runtime-ie. as your ActiveRecord models are loaded-so they will always be up-to-date. For example, given a foreign-key from a customer_id column in an orders table to an id column in a customers table, the plugin creates:

hello, i would like to display a collection of records on one page (e.g. an author record with all his/her books). a record contains a text_area (e.g. a description of the book) and a date_select (e.g. when the book was published). <% for @book in @author.books %> <%= text_area ''book[]'', ''note'' %> <%= datetime_select

Hi, I am doing the following: <% obj.contracts.each do |@contract| -%> ... <%= hidden_field("contract[]", :contractor_id, :index => @contract.contractor.id) %> <%= date_select("contract[]", :starting_on, :index => @contract.contractor.id) %> ... <% end -%> Here are the request parameters: {"commit"=>"Save",

Noob Question 31,265,232 if I''m searching on an object, say order, that has many "order_lines" and I want to display order lines by Quantity ( an attribute of the order_lines ) descending how could I do that without having to do a find() with :order, but something like; Order.order_lines.each do |ol| <!-- code to diplay the line --> how can I determine the field

Hi, I''ve search for documentations on queries with Arel 2 but there is pretty nothing and all I''ve found is for Arel 1 so I''ve run into NoMethodError: undefined method `[]'' for #<Arel::SelectManager:0x00000003f1b820> errors with join syntax. My query is barely simple but involve nesting queries. I have 4 tables. Assets, Deposits, Orders and OrderLines

Hello People, I have a possibly very lame question. I am fairly new to RoR, and I want to make sure I do it "right". I have a model called Invoice, and one called InvoiceLines. Usual story: the table "invoice" has a 1:n relationship with "invoice_lines", which includes invoice_id. Now... the application will have a "new order" button, which will allow

I am using date_select and in some instances it only shows about 10 years worth of choices. Same form on other users shows the whole range. date_select looks like this <%= date_select ''user'',''birthdate'' , :start_year => 1940 %> I would expect to always see 1940-2006 or so , but i dont always do. Is there a way to force the range or explain why i

Hi, being relativly new to RoR, I''m having a problem which I found described in this forum and somewhere else - but with no solution. I know, that it may be bad to mix table and form tags, but the first solution of an in place editing within a table looked nice: Version using form_for: <tr> <%form_for :time_record, :url => { :action => "add_time_record" } do

Hi everyone, I have a order with order_lines use case. On changing the lines, I want to be sure no one else changed the order. So I use lock_version on the order. This works fine if something is changed on the order record. But now i have the situation that I delete, alter and add order lines without changing the order record itself. I have to check and increment the order#lock_version however

I''m trying to select items from a database by their date field. The date data is coming from a form using the date_select helper. The field in the database is named date_notified_on. My controller method is this: def history_date if(@params) @notifications = Notification.find(:all, :conditions => ["date_notified_on = ?",

Hi, I''ve looked on api.rubyonrails.org but I''ve not found how to add to a date_select(object, method, options = {}) a class option to set the class of all the select tags. I''ve tried using "class" => "myclass" in thoose ways: <%= date_select("costo", "data", "class" => "testo" ) %> <%=

Hello, It''s pretty hard giving a practical example on this one. I have a partial which contains some generated Javascript. Something like: order_screen.rhtml ------------------------------------------- <h1>Order</h1> <div id="order_part"> <%=render :partial=>''order_new'' %> </div> <h1>Ordered products</h1>

I have a main form representing the model, let''s call that ''Order'', and a partial displaying its'' OrderLines. I use the bulk update methods to initialize model objects directly from form data, leaving validation of business logic to the model. As AR likes to write stuff before i do an explicit save, I wrap the whole update in a manual transaction. This works

Dates defined chosen with date_select are not coming through once the form is submitted. I have this in a form: <%= date_select ''search'', ''date_start'', :include_blank => true %> <%= date_select ''search'', ''date_end'' , :include_blank => true %> However, when I submit the form params[:search][:date_start]

I can''t get observe_field to do anything with my date_select. Here''s the rhtml code: <%= date_select ''course'', ''lab_start_date'' %> <%= observe_field(:course_lab_start_date, :frequency => 0.5, :update => :course_lab_start_date_div, :url => { :action => ''preview_text''}) %> My

Hi, I could not find an easy way to specify the ''id'' attribute for select inputs of ''date_select'' form helper. I need to set it because I want to retrieve date selects values from a javascript. <%= date_select ''product'', ''expiration'' %> generates <select name="product[expiration(1i)]">

Folks, I think I should start a new thread for this, because a similar one I saw is a bit old and the resolution there doesn''t seem to apply to what I''m running into now. Anyway, my date_select calls are bombing on me with the exception: ---- ActionView::TemplateError (wrong number of arguments (3 for 2)) on line #8 of entries/_dates_form.haml: 8: = date_select(
