Form data not uploading to sqlite database

Hi,

I created a simple form using form_for and partials. When I enter a
value
in text field and click on add button, the data doesn’t get uploaded in
database table.

view/task.html.erb
<%= render :partial => “job_form” %>

<% for job in @jobs %>
<%= job.name %>
<% end %>

view/_job_form.html.erb
<%= form_for(@job, :url => task_path) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.submit “Add” %>
<% end %>

/view/home_login_controller.rb
def task
@job = Task.new
@jobs = Task.all
end

db/_create_tasks.rb
def change
create_table :tasks do |t|
t.string :name
t.timestamps
end
end

db/schema.rb
create_table “tasks”, :force => true do |t|
t.datetime “created_at”, :null => false
t.datetime “updated_at”, :null => false
t.string “name”
end

app/models/task.rb
class Task < ActiveRecord::Base

attr_accessible :title, :body

end

I have done db migration and db schema exists for table but “select *
from
tasks” doesn’t return any rows and therefore UI doesn’t show any form
data.
Can someone please help me debug this issue?

Thanks.

Ankur

So what does happen when you click on the form’s button ? Did you look at
your application logs / server output? At first glance you’re posting to
the wrong url - to create a new task you post to tasks_path where you
have
forced the url to task_path (which would be appropriate for updating an
existing task).

Hi Frederick,

If I change the path to tasks_path, I get the following error while
navigating on to the page which has this form. If I keep task_path,
navigation works fine.

undefined local variable or method `tasks_path’ for
#<#Class:0xa3de690:0xb550f644>

I don’t see any error in development.log when I click on the Add button.
the page re-loads as expected because of “task_path” url but data
doesn’t
persist.

Also, I missed adding create action in controller earlier, have added it
now:

   * def create*
  • Task.create params[:task]*
  • redirect_to :back*
  • end*

Thanks.

Did you add a route for your create action ? That would also explain why
tasks_path raises an exception (I was assuming you had resources :tasks
in
your routes). As Colin says, this sort of stuff is covered by most
tutorials. This will also get you on the path of using standard naming
conventions, which makes things a lot easier.

Fred

Thanks.

Can I suggest that you work right through a good tutorial such as
railstutorial.org (which is free to use online). That will show you
the basics of rails so that you will be able to answer simple
questions yourself.
