When I click on this link in my index view:
<%= link_to "Edit Password", edit_user_path(current_user) %>
I get this error:
NoMethodError in Users#edit
Showing /rubyprograms/dreamstill/app/views/videos/_modal.html.erb where line #3 raised:
undefined method `model_name' for NilClass:Class
Extracted source (around line #3):
1: <div id="boxes">
2: <div id="dialog" class="window">
3: <%= form_for(#video) do |f| %>
This has to do with a partial called _modal that I render into the indexview. It has a form in it.
I also have this in my Videos controller:
def index
#video = Video.new
#videos = Video.paginate(:page => params[:page], :per_page => 20)
end
Why am I getting this error, and how can I fix it?
UPDATE:
Here's my edit action in the Users controller:
def edit
#user = current_user
end
Here's the _modal partial:
<div id="boxes">
<div id="dialog" class="window">
<%= form_for(#video) do |f| %>
<% if #video.errors.any? %>
<div id="errorExplanation">
<h2><%= pluralize(#video.errors.count, "error") %> prohibited this video from being saved:</h2>
<ul>
<% #video.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :video_url %><br />
<%= f.text_field :video_url %>
</div>
<div class="field">
<%= f.label :title, 'Song Title' %><br />
<%= f.text_field :title %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
<%= link_to 'Cancel', '#', :class => 'close' %>
</div>
<div id="mask"></div>
</div>
I believe you are basically having the same problem as last time.
Since you are effectively rendering the edit action—whether it is in a modal or not—you need #video defined again.

I've upgraded to rails 6.1 from rails 6.0 and trying out Hotwire, but I am getting an error when trying to run my application:
wrong number of arguments (given 0, expected 1..4)
Extracted source (around line #1):

my code in my show.html.erb:
<%= turbo_frame_tag 'branch' do %>

Does anybody have an idea what I might have missed during the upgrade process? I ran rails turbo:install and also rails hotwire:install or am I missing something in the turbo frame tag?
The Seller Profile has one seller. I am trying to post the seller profile details and assigning the seller_id to the current_seller. I am however, running into this error. I don't understand why the error says missing parameter because it seems all the needed params have being provided.
Error is get is ActionController::ParameterMissing (param is missing or the value is empty: seller_profiles
def create
#seller_profile = SellerProfile.new(seller_profile_params)
#seller_profile.seller = current_seller
respond_to do |format|
if #seller_profile.save
format.html { redirect_to root_path, notice: 'Seller profile was successfully created.' }
def seller_profile_params
params.require(:seller_profile).permit(:first_name, :other_name, :last_name, :email)
end
<%= form_tag seller_seller_profiles_path do |form| %>
<% if seller_profile.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(seller_profile.errors.count, "error") %> prohibited this seller_profile from being saved:</h2>
<ul>
<% seller_profile.errors.each do |error| %>
<li><%= error.full_message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= label_tag :first_name %>
<%= text_field_tag :first_name %>
</div>
<div class="field">
<%= label_tag :other_name %>
<%= text_field_tag :other_name %>
</div>
<div class="field">
<%= label_tag :last_name %>
<%= text_field_tag :last_name %>
</div>
<div class="field">
<%= label_tag :email %>
<%= text_field_tag :email %>
</div>
<div class="actions">
<%= submit_tag %>
</div>
<% end %>
resources :sellers, only: [:new, :create, :show, :index, :destroy] do
resources :seller_profiles
end
You should use the form_for or the form_with helpers instead of form_tag. Those helper methods will take care of adding the wrapping seller_profile key.
<%= form_for seller_profile do |form| %>
<% if seller_profile.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(seller_profile.errors.count, "error") %> prohibited this seller_profile from being saved:</h2>
<ul>
<% seller_profile.errors.each do |error| %>
<li><%= error.full_message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :first_name %>
<%= form.text_field :first_name %>
</div>
<div class="field">
<%= form.label :other_name %>
<%= form.text_field :other_name %>
</div>
... replicate the same change for the rest of the fields ...
<div class="actions">
<%= form.submit %>
</div>
<% end %>
If the error is (param is missing or the value is empty: seller_profiles, it's because you require :seller_profile, not :seller_profiles in your params.require
I'm making a bloglike application. I want to make it so that blog posts are editable if clicked.
This is my partial that displays all the posts of a user and makes them clickable
<% if #feed_items.any? %>
<% #feed_items.in_groups_of(3, false).each do |feeds| %>
<div class="row">
<% feeds.each do |feed| %>
<div class="col-md-4">
<ol class="posts">
<%= link_to edit_post_path(feed) do %>
<%= render feed %>
<% end %>
</ol>
</div>
<% end %>
</div>
<% end %>
<% end %>
This is the Edit view that it redirects to when a post is clicked:
<% if logged_in? %>
<div class="row">
<%= render 'shared/post_form' %>
</div>
<% end %>
And this is the '_post_form' partial which is the layout for an editable post:
<%= form_for(#post) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field">
<%= f.text_area :content, placeholder: "Compose new post..." %>
</div>
<%= f.submit "Post", class: "btn btn-primary" %>
<% end %>
When I click a post to edit it it does redirect however it gives me the error: "First argument in form cannot contain nil or be empty"
Any suggestions on how to resolve this?
In your controller's edit method you have to set #post like,
def edit
#post = Post.find(params[:id])
end
I am trying to implement simple form in home#index page using:
<%= render "forms/form"%>
Form look like this:
<%= form_for(#form) do |f| %>
<% if #form.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#form.errors.count, "error") %> prohibited this form from being saved:</h2>
<ul>
<% #form.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :defect %><br />
<%= f.text_field :defect %>
</div>
<div class="field">
<%= f.label :region %><br />
<%= f.text_field :region %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
But when I access that page, I got this error message:
undefined method `model_name' for NilClass:Class
First of all I though it is because my model name is also Form, but then I checked Rails 3 reserved words, but there wasn't "form" !
Thanks in advance!
In home controller, set the instance variable #form in the index action as:-
def index
#form = Form.new
end
Your #form instance variable's value is nil. You should set it in controller.
I have the following view page in my test_app:
<p id="notice"><%= notice %></p>
<p>
<strong>Box count:</strong>
<%= #job.box_count %>
</p>
<p>
<strong>Install date:</strong>
<%= #job.install_date %>
</p>
<%= link_to "Back", :back %>
I have the following ruby code in my jobs_controller show method:
def show
#job = Job.find(params[:job_id])
end
The parameters being passed through to the view are ("customer_id" and "id" for the job) as follows:
{"customer_id"=>"1", "id"=>"23"}
When I load the view for any job, I get the following error:
Couldn't find Job without an ID
I must have an error in my show method, but I am unsure exactly what I am doing wrong.
Any ideas?
It looks as though the issue is that my form is not saving the data to the table, here is my form:
<%= form_for([#customer, #job]) do |f| %>
<% if #job.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#job.errors.count, "error") %> prohibited this job from being saved:</h2>
<ul>
<% #job.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :box_count %><br>
<%= f.number_field :box_count %>
</div>
<div class="field">
<%= f.label :install_date %><br>
<%= f.text_field :install_date %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Any idea why the data is not being saved?
You should be using :id, not :job_id:
def show
#job = Job.find(params[:id])
end
