rails how to access custom input form field - ruby-on-rails-3

Hello i have nested form and i need to access my own input tag after submit in model via function
accepts_nested_attributes_for :address, :reject_if => lambda { |a| a[:city].blank? }
I have User form and Address form is nested, i add checkbox to the form. How can i access it ?
example:
<%= f.label :telephone %><br />
<%= f.text_field :telephone %>
<input type="checkbox" id="addAddress"/> Fill Address
<%= f.fields_for :address do |builder| %>
<%= builder.label :name, "Name" %><br />
<%= builder.text_field :name, :disabled => true %>
I need access checkbox status via lambda function, is it possible? thank you

You could use an accessor like this in your model:
attr_accessor :add_address
and in your form:
<%= f.check_box :add_address %>
then in your lambda you can check the value of add_address

Devise nested form not creating profile

Rails 5.0.1
Devise 4.2.0
Hello, I'm building an app in which the user must fill a form to sign up, which includes the registration info for devise, and some personal info por their profile. I have made the models for user and profile, established their one to one relation, and added accept_nested_attributes_for :profile inside the user. I have also modified the registrations views to include f.fields_for for the profile, and until that point everything seems to work fine.
But, when I try to create a new user, and fill the required information, I get an error inside the view (from devise I guess) saying:
1 error prohibited this user from being saved
Profile user must exist
I have already followed many guides on how to create a nested form with devise, and none of them seem to have this issue, and I have also searched a lot with no answer. Here are some snippets from my registration controller, user and profile model, and registrations/new view:
registrations_controller
class Users::RegistrationsController < Devise::RegistrationsController
before_action :configure_sign_up_params, only: [:create]
before_action :configure_account_update_params, only: [:update]
def new
build_resources({})
resource.build_profile
respond_with self.resource
end
protected
def configure_sign_up_params
devise_parameter_sanitizer.permit(:sign_up,
keys: [:email, :password,
:password_confirmation,
profile_attributes: [:name, :art_name,
:birth_date, :location]])
end
User model
class User < ApplicationRecord
has_one :profile, dependent: :destroy
before_create :build_profile
accepts_nested_attributes_for :profile
# Devise configuration.....
end
Profile model
class Profile < ApplicationRecord
belongs_to :user
end
Registrations/new view
<h2>Nueva Cuenta</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<%= f.fields_for :profile do |b| %>
<div class="field">
<%= b.label :name, "Nombre" %><br />
<%= b.text_field :name %>
</div>
<div class="field">
<%= b.label :art_name, "Nombre artistico" %><br />
<%= b.text_field :art_name %>
</div>
<div class="field">
<%= b.label :birth_date, "Fecha de nacimiento" %><br />
<%= b.date_field :birth_date %>
</div>
<div class="field">
<%= b.label :location, "Ubicacion" %><br />
<%= b.text_field :location %>
</div>
<% end %>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :password %>
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
<%= render "devise/shared/links" %>
My guess is that it has something to do with the sanitizers, I'm not completely sure how do I pass each attribute through, since most of the guides that explained this did with an older version of devise.
Thanks for your attention.
in your profile model, try this:
belongs_to :user, optional: true
it works for me

Pass a variable to text_field without changing form

I have _form.html.erb
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :password %>
<%= f.password_field :password %>
Now if I render this form in homepage, HTML code should be:
<label for="session_name">Name</label>
<input id="session_name" name="session[name]" size="30" type="text">
...
If I change my _form.html.erb to:
<%= f.label :name %>
<%= f.text_field :name, disabled: true %>
...
HTML code should be:
...
<input disabled="disabled" id="session_name" name="session[name]" size="30" type="text">
...
But, I don't want to change my _form.html.erb, so how can I pass the disabled: true into my form? I tried to use render partial: but don't know syntax.
I just learn Ruby on Rails for 2 weeks, so please help me.
i donno why u wnt to do so but u can solve the prob by this method. Try doing-
in application helper, add method -
def add_disabled
#i suppose that u want the field to be disabled in the users controller for edit action but not for other controllers or actions
return "disabled='disabled'" if params[:controller] == "users" and params[:action] == "edit"
end
in _form.html.haml
= f.text_field :name, #{add_disabled}
this will call the helper method and return "disabled='disabled'" depending upon the controller and action

Rails3 acts_as_taggable with a form

I've just started working with the acts_as_taggable gem. Really liking it so far, but I am a bit unclear about how to use this gem with a form.
class Photo < ActiveRecord::Base
acts_as_taggable_on :tags
end
In my form for Photos I am trying to implement a series of checkboxes for the user to assign tags to their photo:
<%= f.label :tag_list %>
<%= f.check_box :tag_list, "landscape" %>
<%= f.check_box :tag_list, "people" %>
When viewing the form I get this error:
NoMethodError in Photos#edit
...line #19 raised:
undefined method `merge' for "landscape":String
Extracted source (around line #19):
18: <div class="float_tag">
19: <%= f.check_box :tag_list, "landscape" %>
Any thoughts as to how I should create my form?
I'm assuming your <form> looks something like this:
<%= form_for(#photo) do |f| %>
<%= f.label :tag_list %>
<%= f.check_box :tag_list, "landscape" %>
<%= f.check_box :tag_list, "people" %>
<% end %>
You should change up your f.checkbox lines a bit:
<%= form_for(#photo) do |f| %>
<%= f.label :tag_list %>
<%= f.check_box :tag_list, { :multiple => true }, 'landscape', nil %>
<%= f.check_box :tag_list, { :multiple => true }, 'people', nil %>
<% end %>
Which will post something like this when submitted (with only people selected, for example):
{ :post => { :tag_list => ['', 'people'] } }
For anyone trying to get this to work with Rails 4 and strong parameters, I also had to permit the the tag_list param as an array.
params.require(:clip).permit(
:name, :other_params, { tag_list: [] }
)

Rails: Accessing data of other SQL table in View

I don't understand how access data from my View in other table.
I have few models. First is User, second is UsersPreferences. So i have settings page for users and code looks like this:
<%= render 'shared/error_messages', :object => f.object %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
...
<div class="checkbox">
<%= f.check_box :notification_about_new_followers %>
<%= f.label 'Notify via email about new followers' %><br />
</div>
This code works (User has row notification_about_new_followers) but i want to change it. I decided that better way is keep preferences in other table. So i created model UsersPreferences which has user_id and flag 'notify_about_new_followers'. I tried to rewrite my view like that:
<%= render 'shared/error_messages', :object => f.object %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
...
<div class="checkbox">
<%= f.check_box UsersPreferences.find_by_user_id(#user.id).notify_about_new_followers %>
<%= f.label 'Notify via email about new followers' %><br />
</div>
But when i visit page with code i get such error
undefined method `true' for #<User:0x007f8ac180dee8>
How can i solve this error?
User model:
class User < ActiveRecord::Base
attr_accessible :name, ... , :notification_about_new_followers
...
has_one :users_preferences
end
UsersPreferences model:
class UsersPreferences < ActiveRecord::Base
belongs_to :user, :class_name => "User"
attr_accessible :notify_about_new_followers
end
This line:
<%= f.check_box UsersPreferences.find_by_user_id(#user.id).notify_about_new_followers %>
is causing the error. UsersPreferences.find_by_user_id(#user.id).notify_about_new_followers is true, so essentially that line reads:
<%= f.check_box true %>
And like the error says, there is no 'true' attribute for your UserPreferences model.
To fix this you'll need to first read up on MVC (Model-View-Controller). Without knowing how MVC works, you'll never be able to move forward with Rails. There are a lot of great resources out there, just google "Model View Controller for rails". Here is a good one. A little goofy, though... if that's not your style, try another link.
After you have learned that, look up the rails helper fields_for, and there you will find your answer.

How to create Rails3 forms for embedded Mongoid models?

How to create form for new User model with embedded Phone model?
I've found solution for creating form to add Phone for existing User but how to do that at the same time i create new User?
You have to create a nested form
<%= form_for #user, :url => users_path do |f| %>
<%= f.label :name, "Name:" %> <br />
<%= f.text_field :name %>
<%= f.fields_for :phone do |p| %>
<%= p.label :number, "Phone Number" %> <br />
<%= p.text_field :number %>
<% end %>
<% end %>
