I have been using Ruby on Rails for an app and have a long line of forms I am trying to use in the process. They have all been working perfectly but when I select submit after filling out all the information, the screen doesn't change on in 'inspect' it says the form is not assigned to any user.
I checked each form controller and I had something like this:
def create
#crew_applicant_form = CrewApplicantForm.new(crew_applicant_form_params)
#crew_applicant_form.user = current_user
respond_to do |format|
if #crew_applicant_form.save
format.html { redirect_to crew_applicant_form_url(#crew_applicant_form), notice: "Crew applicant form was successfully created." }
format.json { render :show, status: :created, location: #crew_applicant_form }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: #crew_applicant_form.errors, status: :unprocessable_entity }
end
end
end
Any suggestions on what I'm doing wrong here? I can send over the code html and model if need be

I install Ubuntu, RoR and all RoR components. Then I update question.
I need to get the form as in this screenshot. I need this part. So that it appears after clicking the Add button. I understand the logic of adding a form after clicking a button, but I can’t understand how the code of the form itself should look. Even a form with only text_field launches a site with an error 500. I may not know a lot, I'm just learning RoR.

Add a #todo instance variable in the index action
def index
#title = 'Задачи'
#projects = Project.all
#todos = Todo.all
#todo = Todo.new
#project_array = #projects.map { |project| [project.title, project.id] } #minimize the use of logic in your views.
end
Add the form in your view.
<%= form_for #todo do |todo| %>
<%= todo.text_field :text %>
<%= todo.select :project_id, options_for_select(#project_array) %>
<%= todo.submit "Отмена" %>
<%= todo.submit "ОК" %>
<% end %>
If you have a TodoController with create and update action
<%= form_with(model: #todo, local: true) do |todo| %>
<%= todo.text_field :text %>
<%= todo.select :project_id, options_for_select(#project_array) %>
<%= todo.submit "ОК" %>
<% end %>
This will always point to the create action of the TodoController
The problem is #todo is not referenced in your index_controller.rb, so your index_controller.rb #index action must be:
def index
#title = 'Задачи'
#projects = Project.all
#todos = Todo.all
#todo = Todo.new
end
Then in your index.html.erb
<%= form_for #todo do |todo| %>
<%= todo.text_field :text %>
<%= project_array = #projects.map { |project| [project.title, project.id] } %>
<%= todo.select (:project_id, option_for_select(project_array)) %>
<%= todo.submit "Отмена" %>
<%= todo.submit "ОК" %>
<% end %>
try to install simple_form_for gem. It will allow you makes form without any troubles.
I'm working on a Rails 5 API application and Im having trouble when trying to render json. Take that simple controller:
module Api
module V1
class UsersController < ApplicationController
def sign_up
#user = User.new user_params
if #user.save
render json: {status: :ok, user: #user.to_json }
else
render json: { status: :error, errors: #user.errors }, status: :unprocessable_entity
end
end
end
end
end
When I test this request with a simple spec:
RSpec.describe Api::V1::UsersController, type: :controller do
context 'As an unregistered user' do
context 'signing up with valid params' do
let(:valid_params) do
{ name: 'Test User', email: 'test#test.com', password: '123456789', password_confirmation: '123456789' }
end
it 'returns a 200 status' do
post :sign_up, params: { user: valid_params }
expect(response.status).to eq 200
end
end
end
end
I get an error thrown at me:
Failures:
1) Api::V1::UsersController As an unregistered user signing up with valid status returns a 200 status
Failure/Error: render json: {status: :ok, user: #user.to_json }
NoMethodError:
undefined method `unpack' for nil:NilClass
# ./app/controllers/api/v1/users_controller.rb:10:in `sign_up'
# ./spec/controllers/api/v1/users_controller_spec.rb:15:in `block (4 levels) in <top (required)>'
I'm not using any gems that alter rendering yet so I'm really lost of what might be the problem. Thanks in advance.
I just deployed my first rails 4 app to a VPS and now I cannot write to the production database. Everything deployed fine (migrations etc) and I can log on the mysql database with sequel pro and see it is all there however when I try create a user using the app's new user form instead of notifying 'Thank you for registering' (as it does in development) it asks me to login to proceed. No record is created in the database.
I can see in the log that it is binding show rather than the users id to the :id parameter and therefore redirecting to login rather than creating a session. Why would this be?
This is the app log

Guy I got something strange in my project
Now I got old ruby on rails project to develop some notes in it after I activate the commands
bundle
bundle exec rake db:create
bundle exec rake db:migrate
rails s
First the application asked me to install mysql2 0.3.14 and after installed it I got the error
log writing faild. invalid byte sequence in US-ASCII
and I solved it by added the #encoding: utf-8 in every first line in the project models
and finally now I can open my project well but
I found when I read data from my DB it work well when tried to insert or update any data from my MYSQL DB nothing happen with me !!!!! I thought that my DB user only take permissions to read only from the DB but after checked the user permissions I found it takes all the permissions
So can any one explain to me why I go this issue ????
This is a simple code to insert into my MYSQL DB
the View code
<%= form_for(#category) do |f| %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :icon %><br>
<%= f.file_field :icon %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
controller code
def create
#Just test to insert fixed data to my DB but also not insert any thing
#category =Category.new(:title => 'eeeee', :icon_file_name => 'xxx', :slug => 'sug')
##category =Category.new(:title => params[:title], :icon_file_name => params[:icon], :slug => params[:slug])
##category = Category.new(category_params)
respond_to do |format|
if #category.save
format.html { redirect_to #category, notice: 'Category was successfully created.' }
format.json { render action: 'show', status: :created, location: #category }
else
format.html { render action: 'new' }
format.json { render json: #category.errors, status: :unprocessable_entity }
end
end
end

Seems like you didn't sanitize your params. In Rails 4 strong parameters have been introduced in order to increase security of untrusted sources posting data to your database.
So in your controller you have to add a private method (if you generated it with scaffolding it should be already present) to say which parameters to accept.
in your case should be something like
def category_params
params.require(:category).permit(:title, :icon_file_name, :slug, :whatever_other_param_you_need)
end

I am trying to connect to a separate mysql database than what my rails app is on. I am trying to connect to a database of guitar tabs so that users can search for specific songs.
I have my database.yml configured to:
tabs:
adapter: mysql2
encoding: utf8
database: (dbname)
username: (username)
password: (pass)
host: hostname.rds.amazonaws.com
port: 3306
So far I have tab.rb as my model:
class Tab < ActiveRecord::Base
self.abstract_class = true
establish_connection ('tabs')
end
finally, my controller
class TabController < ApplicationController
def listTabs
#tabs = Tabs.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: #tabs }
end
end
def showTabs
#tabs = Tabs.find_by_sql "SELECT * FROM gp"
respond_to do |format|
format.html # index.html.erb
format.json { render json: #statuses }
end
end
end
I'm new to rails and I really want to get this to work. If you are able to help me just run the query "SELECT * From gp" and display it in my view, I will love you forever.
Thanks for your help!
in your model the name is Tab and you use in controller Tabs i.e is wrong, please use Tab.all or Tab.find_by_sql
