How can it be that some members of the development team have no problem with sending Post request with Russian symbols from form, but other members - have? All members are using Ubuntu.
The error is: "There were problems with the following fields: Username should use only letters, numbers, spaces, and .-_# please."
model:
validates_presence_of :username, :email
validates_uniqueness_of :username
view:
<%= form_for #user do |f| %>
<%= f.label :username %>
<%= f.text_field :username %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.submit "Change" %>
<% end %>
Any suggestions?
Thanks!
That looks like a validation error, but your validations don't seem to include it. Are you sure you're looking at the right model file?

I have a rails app where I can create and edit records. I've created a form to enter data which works fine when I use the new/create actions. It will create a record no problem. But when I hit the edit action it gives me an undefined method 'model_name' for NilClass:Class.
I'm not sure what this means. Can someone give me a hand?
Form:
<%= form_for(#patient) do |f| %>
<%= f.label :Patient_Last_Name %>
<%= f.text_field :patient_last %>
<%= f.label :Patient_First_Name %>
<%= f.text_field :patient_first %>
<%= f.label :Patient_DOB %>
<%= f.date_select :patient_dob %>
<%= f.label :Primary_Diagnosis %>
<%= f.collection_select(:diagnosis_id, Diagnosis.all, :id, :diagnosis_name)%></br>
<%= f.label :Primary_Physician %>
<%= f.collection_select(:physician_id, Physician.all, :id, :physician_name)%></br>
<%= f.button :submit %>
<% end %>
View Code:
<td><%= link_to 'Edit', edit_patient_path(patient), :class => 'btn btn-close btn-mini'%></td>
Controller Code:
def edit
#patient = Patient.find(params[:id])
end
Edit view:
<%= render 'form' %>
When I remove the partial render from the form, the URL will go to the correct route/url. But I keep getting that error when the form partial is rendered.
There was an extra end statement in my controller which was cutting off half of the class which included the edit action. This was not allowing me to use the edit action. Once this typo was fixed things started working normally.
Sorry for the confusion.
I have a form to create adverts.
Controllers:
def edit
#engines = Engine.all
#car = Car.find(params[:id])
end
def update
#car = Car.find(params[:id])
if #car.save
redirect_to root_path
end
end
My routes:
resources :adverts
Create.html.erb
<%= form_for #car, :url => adverts_path do |f| %>
<div><%= f.label :name %><br />
<%= f.text_field :name %></div>
<%= hidden_field_tag :model_id, params[:model_id] %>
<%= select_tag :engine_id, options_from_collection_for_select(#engines, "id", "name",:selected=>#car.engine_id) %>
<div><%= f.submit "Create car!" %></div>
<% end %>
I can create advert, but I can't to update it.
edit.html.erb
<%= form_for #car, :url => adverts_path do |f| %>
<div><%= f.label :name %><br />
<%= f.text_field :name %></div>
<%= hidden_field_tag :model_id, params[:model_id] %>
<%= select_tag :engine_id, options_from_collection_for_select(#engines, "id", "name",:selected=>#car.engine_id) %>
<div><%= f.submit "Update car!" %></div>
<% end %>
when I submited my form, I have an error - No route matches [PUT] "/adverts"
$ rake routes:
adverts GET /adverts(.:format) adverts#index
POST /adverts(.:format) adverts#create
new_advert GET /adverts/new(.:format) adverts#new
edit_advert GET /adverts/:id/edit(.:format) adverts#edit
advert GET /adverts/:id(.:format) adverts#show
PUT /adverts/:id(.:format) adverts#update
DELETE /adverts/:id(.:format) adverts#destroy
I need help.
When you are updating you have to let Rails know which object you want to update by passing an id.
In edit.html.erb change:
<%= form_for #car, :url => adverts_path do |f| %>
to:
<%= form_for #car, :url => advert_path(#car) do |f| %>
By the way, I find your code very strange. Why don't your model names match your controllers and routes? I mean you are creating an advert but your model is called car. That doesn't make any sense. Either call it car or advert, but don't mix them.
If you used RESTful routing, you don't need to specify a url, just need:
<%= form_for #car do |f| %>
The form can know #car is new record, or saved record, so it will send appropriate http method.
And in your update action:
def update
#car = Car.find(params[:id])
if #car.update_attributes(params[:car])
redirect_to root_path
end
end
I got myself in a similar situation today with a mismatched resource and model name. I agree the model and controller names need to correlate, but you can override the routes name to be whatever you want.
resources :cars, path: "adverts"
Along with RESTful routing
<%= form_for #car do |f| %>
You may also want to make sure your url: path is singular on the #form_form.
Forgive me if this has been answered. I spent a few hours searching for the answer to this both here and on Google.
I'm just getting started with Ruby on Rails. I'm trying to update a model with data from an API response after saving the data originally submitted via the form to two different models.
So basically I have a User model and a Character model. The sign up form collects data on the user and their character. In order to make an API request I have to at least get a few details about the character to pass in as part of the requested attributes (i.e. name, realm).
So I'm using a form_for with nested attributes:
<%= form_for(#user) do |f| %>
<%= render 'shared/error_messages' %>
<%= f.label :username %>
<%= f.text_field :username %>
<%= f.label :first_name %>
<%= f.text_field :first_name %>
<%= f.label :last_name %>
<%= f.text_field :last_name %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.label :password_confirmation, "Password Confirmation" %>
<%= f.password_field :password_confirmation %>
<%= f.fields_for :characters do |builder| %>
<%= builder.label :realm %>
<%= builder.text_field :realm %>
<%= builder.label :name %>
<%= builder.text_field :name %>
<% end %>
<%= f.submit "Sign Up" %>
<% end %>
This successfully submits all of the user info submitted to the User model and the realm and name submitted to the Character model. No problems there. However, I have several more fields that I want t fill in for the Character records just created from the API that provides all of the character info. What is the most efficient way to do this so that after the form submits, it updates the record (or adds data prior to save the record) with the data coming back from the API.
I don't need help on the specific fields and data returned. I have that all working, I'm just looking for a way to make the API request and complete the record with all data immediately after the form submits.
Suggest to use callback (:after_create) .
Depending upon the API processing you can choose between them .
:after_save
:before_save
:before_create
With any callback just get the data from your API and fill other character info's.
Hope that helps . Good luck .
It's my first time here, and first time I use nested_form gem. Everything seemed to be ok, but the data from my "parent" model doesn't save.
Here is my code
<%= nested_form_for #project do |f| %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<%= f.fields_for :tasks %>
<p><%= f.link_to_add "Add a task", :tasks %></p>
<%= f.submit %>
<% end %>
so, when I "submit", just the tasks are saved ok, but not the project name.
Any clue for me? did I miss something??
You need to add the attribute. eg name to attr_accessible.
# app/models/project.rb
class Project < ActiveRecord::Base
has_many :tasks, :dependent => :destroy
accepts_nested_attributes_for :tasks, :allow_destroy => true
attr_accessible :name,:tasks_attributes ## <-- you need this line
end
Your fields_for declaration isn't quite right
<%= f.fields_for :tasks %>
Should be
<%= f.fields_for :tasks do |task_builder| %>
you are also missing an end for that declaration and a render to render the partial that has the nested fields for the associated object.
So you should end up with something like this
<%= f.fields_for :tasks do |task_builder| %>
<%= render 'task_fields', :f => task_builder %>
<% end %>
<p><%= f.link_to_add "Add a task", :tasks %></p>
That should do the trick. all you need to do now is create a _task_field.html.erb partial and add the task fields to it in the usual way using f.label, f.text_field etc...
p.s.
Your code could not possibly have ever worked. You would have had errors so something is probably missing from your opening post.
In my first rails app I'm trying to use form_for and fields_for to create a nested object form. So far so good, but I can't figure out how to access the sub-object while in the fields_for block. I've pre-populated a field in the sub-object with data that I want to show in the user instructions.
Models
Garage:
has_many :cars, :dependent => :destroy
accepts_nested_attributes_for :cars
Car:
belongs_to :garage
Garage Controller
def new
#garage = Garage.new
for i in 1..5
#garage.cars.build :stall_number => i
end
end
_form.html.erb
<%= form_for #garage do |f| %>
<%= f.label :title, "Garage Name" %><br />
<%= f.text_field :title %>
<% f.fields_for :cars do |builder| %>
<p>Enter license for car parked in stall: <%= car.stall_number %></p>
<%= f.label :license, "License #:" %><br />
<%= f.text_field :license %>
<%= end %>
<%= end %>
As you can see, inside the builder block for :cars, I want to show, in my user instructions, the field: car.stall_number (populated in my controller with an integer):
<p>Enter license for car parked in stall: <%= car.stall_number%></p>
I've tried a many different ideas: #car.stall_number, object.car.stall_number, etc. No joy. Multiple searches and a look at the fields_for source code haven't helped my understanding. I would appreciate any guidance.
Update: For clarification, per Dan's suggestion I have tried builder.stall_number but it results in a
NoMethodError: undefined method 'stall_number' for #<ActionView::Helpers::FormBuilder:0x00000102a1baf0>
I just dealt with this today myself.
You can access the object of the fields_for through:
builder.object
where builder is your fields_for form builder object. In your particular case, you can say:
<p>Enter license for car parked in stall: <%= builder.object.stall_number%></p>
That should do it for you!
The way you are trying is does not work because you want to access car without filling that variable for data.
I guess you want to have multiple blocks of stalls, where you can enter license plates. For each stall you will need your own fields_for.
I would suggest something like that:
<%= form_for #garage do |f| %>
<%= f.label :title, "Garage Name" %><br />
<%= f.text_field :title %>
<% for i in 1..5 %>
<% f.fields_for #garage.cars[i] do |builder| %>
<p>Enter license for car parked in stall: <%= builder.stall_number%></p>
<%= builder.label :license, "License #:" %><br />
<%= builder.text_field :license %>
<% end %>
<% end %>
<% end %>
Within the fields_for you need to use the form object you define there, in this case builder. Since the data there are not mapped to the outer form (f), but to the cars object (builder).
