OK this is weird, I have basically the following classes:
class PriceProfile < ActiveRecord::Base
has_many :prices
has_many :price_profile_date_ranges
attr_accessible :name, :price_profile_date_ranges_attributes
accepts_nested_attributes_for :price_profile_date_ranges
}
class PriceProfileDateRange < ActiveRecord::Base
attr_accessible :end_date, :price_profile_id, :start_date, :prices, :prices_attributes
has_many :prices, :dependent=>:destroy
belongs_to :price_profile
accepts_nested_attributes_for :prices
}
class Price < ActiveRecord::Base
attr_accessible :price_profile_date_range_id, :price_profile_id, :product_id, :value
belongs_to :price_profile
belongs_to :price_profile_date_range
belongs_to :product
}
A price profile defines a pricing scheme for a particular product whose price changes over time. The date ranges over which a price is applied is stored in the price_profile_date_range table and finally the prices table holds all the prices. I'm using the following controller & view to create the form here for setting prices while creating a date range. Basically the form has a start and end date fields and a grid i.e it would have a list of texteboxs against all products to enter the price.
This is the view:
.row
.span9
= simple_form_for(#price_profile_date_range, :class=>'well') do |f|
.form-inputs
= f.input :start_date, :required => true, :as => :string, :input_html =>{:class=>'datepicker'}
= f.input :end_date, :required => true, :as => :string, :input_html =>{:class=>'datepicker'}
= f.input :price_profile_id, :as=>:hidden
%table.table.table-bordered.table-condensed.table-striped
%tr
%td
- #products.each do |product|
%td
=product[:name]
%td
- f.fields_for(:prices) do |price_element|
= price_element.input :value, :class=>'span1'
= price_element.input :price_profile_id, :as=>:hidden
= price_element.input :price_profile_date_range_id, :as=>:hidden
= price_element.input :product_id, :as=>:hidden
.form-actions
= f.button :submit
This isnt exactly the final form - the problem is that the f.fields_for line doesn't seem to execute. In the controller I initialise the #price_profile_date_range object with a set of prices. If I do a raise inspect it shows all the price objects even in the view however the fields_for doesn't execute at all. I'm pretty stuck here real badly.
Try changing the - to a = - sounds silly but maybe that's the problem.

i have a form consists of the following models

<%= f.association :employee_department, as: :select %>
<%= f.input :counselor_supervisor_id , collection: EmployeeDepartment.all, as: :grouped_select, group_method: :counselor_supervisors %>
<% end %>
the dropdown list appears like this:
If I added an employee which belongs to the first department "Business Administration", the form will be displayed correctly like this:
Update: after adding label_method: :to_label, so my form became like this :
<%= simple_form_for(#batch_counselor_supervisor) do |f| %>
<%= f.error_messages %>
<%= f.association :employee_department, as: :select %>
<%= f.input :counselor_supervisor_id ,
collection: EmployeeDepartment.all, as: :grouped_select, group_method: :counselor_supervisors, label_method: :to_label %>
<% end %>
the employee name displayed correctly but still the department name not displayed correctly as the following image:
Is this SQLite3 issue ? and What can I do in order to solve this if it sqlite3 issue or not.
From what I see, you only have an issue with the labels not being displayed correctly. Could you try to explicitly set the method on your input:
label_method: :to_label
For more information have a look at https://github.com/plataformatec/simple_form and search for *label_method*
What are the actual relevant rows in your Employee table and your EmployeePosition table?
In your Employee table you happen to have these 2 columns;
employee_position_id
employee_position.
Since employee_position is also a table name, it's bad/reduntant model structure which might be confusing your include method of the query. It's possible that in your tables, the rows are fully filled out to complete the first query, but not for any of your other queries even though you think it is.
i have the following nested form :
<%= form_for #contrat,:url => backend_orders_update_report_url(#contrat) do |f| %>
<%= f.fields_for :contrat_lines do |fcl| %>
<%= fcl.object.inspect %>
<% end %>
<% end %>
the output is the following :
nil
In the nested forms i want to display a few elements not as form but as raw text and a few ones as form field. Usually in a form by doing f.object.name, i would access the name and be able to display it as I want. However, here if i do fcl.object, there is only nil. It should display the inspection of a contrat_line object.
Is it possible to access the data in a nested form?
EDIT :
the controller action :
def show_report
#contrat = Contrat.find(params[:id])
end
Here is what models look like with the relation at the beggining :
ContratLine :
class ContratLine < ActiveRecord::Base
include Priceable
belongs_to :contrat
belongs_to :good
#a enlever ici et dans la base
attr_accessible :active_start,:active,:good_id,:pricing,:contrat
validates :active_start, :presence=> true,:if => "active"
validate :active_start_smaller_than_active_stop
validate :active_start_day_cannot_be_greater_than_28
has_one :pricing, :as => :priceable, :dependent => :delete
before_validation :convert_month_year_to_date
after_save :set_user_subscription_date
Contrat :
class Contrat < ActiveRecord::Base
has_many :contrat_lines, :dependent => :delete_all
belongs_to :user
attr_accessible :user_id,:pricing_id,:state,:adresse_id,:adresse,:payment,:adresse_attributes,:automatic,:start_date,:end_date
enum_attr :state, %w(basket waiting_data to_confirm paid) do
labels :basket=>'Panier', :to_confirm=>'Non payé',:paid=>'Payé'
end
enum_attr :payment, %w(debit_card wire_transfer cheque direct_debit)
belongs_to :adresse
accepts_nested_attributes_for :adresse, :allow_destroy => true
scope :by_state, lambda { |state| where("state = ?",state) }
scope :last_automatic, where("automatic = true").order("invoice_date DESC")
scope :last_with_adresse, where("state != 'basket'").order("invoice_date DESC")
before_validation :set_numbers
You're missing an accepts_nested_attributes_for :contrat_lines as well as :contrat_lines_attributes in attr_accessible
Im building a report system which uses a sort of meta question model. Questions are previusly saved in the database, and then depending of the type of report some questions are taken from the database.
Wanting to keep things DRY, i'm trying to figure out a way to pass the information of the Variable model to my report_header with no avail.
In the new action i have:
reportBody = #report_head.report_bodies.build(:variable_id => a.id)
#report_head.variables #modified, thx.
all i need is to pass the attributes from the Variable to report_head in a DRY way.
If you need to know my models:
class Variable < ActiveRecord::Base
attr_accessible :id,:break_point, :description, :name, :time_frequency, :v_type
has_many :report_bodies
has_many :report_heads, :through => :report_bodies
end
class ReportHead < ActiveRecord::Base
attr_accessible :email, :name , :report_bodies_attributes, :report_bodies, :variables_attributes
has_many :report_bodies
has_many :variables, :through => :report_bodies
accepts_nested_attributes_for :report_bodies
end
class ReportBody < ActiveRecord::Base
attr_accessible :report_head_id, :variable_value, :variable_id, :variables_attributes, :report_heads
belongs_to :report_head
belongs_to :variable
end
Update
I updated the model as suggested, and modified the way to call the variables. However im still confused about how to use it in the view, if i do something like:
<%= f.fields_for :variables do |variable| %>
<%= variable.text_field :name, :value => :name, :class => 'text_field' %>
<% end %>
it prints a string instead of the actual name.
You have define wrong name association, your association of ReportBody should be:
belongs_to :report_head
belongs_to :variable
This is not correct:
#report_head.report_bodies.build(:variable_id => a.id,:report_head_id =>#report_head.id)
chang it to:
#report_head.variables.build(:variable_id => a.id)
it's better, you don't have to set report_head_id. And this is wrong:
#report_head.report_bodies.variables
If you want to get all variables belong to #report_head, you just need using:
#report_head.variables
I've been getting the UnkownAttributeError for no particular reason, my models seem to be setup correctly...
School.rb
class School < ActiveRecord::Base
attr_protected :id, :created_at, :updated_at
#relationships
has_many :users
accepts_nested_attributes_for :users
end
My School model used to have the following, but it produced a MassAssignmentSecurity error for the user fields:
attr_accessible :country, :name, :state_or_province, :users_attributes
User.rb
class User < ActiveRecord::Base
attr_accessible :email, :password, :password_confirmation, :remember_me, :username, :instructor_id, :first_name, :last_name, :school_id
#relationships
belongs_to :school
end
new.html.haml
= simple_form_for #school do |f|
.well
= f.input :name, :as => :hidden
= f.input :country, :as => :hidden
= f.input :state_or_province, :as => :hidden
.well
= f.simple_fields_for #school.users.build do |user_form|
= user_form.input :first_name, :required => true
= user_form.input :last_name, :required => true
= user_form.input :username, :required => true
...
= f.button :submit, "Next"
Note: #school is being populated in my new action from session information gathered on the previous page, I'm making a multi-step form. The school data is perfectly valid, if I was to remove the user form it would have no trouble saving the school.
The specific error message I'm getting in my create action:
ActiveRecord::UnknownAttributeError in SchoolsController#create
unknown attribute: user
And the sent params looks a little like this:
{"school"=>{"name"=>"Elmwood Elementary", "country"=>"38",
"state_or_province"=>"448", "user"=>{"first_name"=>"joe",
"last_name"=>"asdas", "username"=>"asasdads",
"email"=>"asdasd#sdas.ca", "password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]"}}, "commit"=>"Next"}
Is this maybe a bug with either Devise or simple_form? I'm using Rails 3.2.3
Ok, so apparently I needed to provide the symbol :users - the name of the relationship as my first argument for it to work.
I am very new to rails development.
I am creating a simple backend for my portfolio site.
I am not sure about the title of this question. A previous question I asked maybe too convoluted. So I am simplifying it.
Im using 3 models: Post, Attachment, Attachment_Category
I have a form that I use to:
Draft the post with a title, content and a category.
Display attachment categories in a drop down (slideshow, image, video)
Upload the attachment(s).
I have implemented steps 1 and 2.
For step 3: I want it so that when I finally hit submit on the form, the attachment_category_id is saved to the attachment table.
I have the following relationships:
Post.rb
class Post < ActiveRecord::Base
has_many :attachment_categories, :through => :attachments
has_many :attachments,:dependent => :destroy
accepts_nested_attributes_for :attachments
validates_presence_of :title, :content, :category
end
Attachment.rb
class Attachment < ActiveRecord::Base
belongs_to :post
belongs_to :attachment_category
#paperclip
has_attached_file :photo, :styles =>{
:thumb => "100x100#",
:small => "400x400>"
}
end
Attachment_category.rb
class AttachmentCategory < ActiveRecord::Base
has_many :posts , :through => :attachments
has_many :attachments
validates :category_name, :presence =>true
end
So I have accomplished Steps 1, parts of step 2 and step 3.
With my solution, I am able to upload just one attachment.
But it works: The attachment gets saved to the Attachments table with the post_id and the attachment_category_id.
The following code is from _form.html.erb which gets sent to post_controller.rb.
Truncated code:
.....
<%= f.fields_for :attachments do |attach| %> <br>
<%= attach.collection_select :attachment_category_id, AttachmentCategory.all, :id, :category_name %>
<%= attach.file_field :photo %> <br>
<% end %>
.....
