Rails database table relational issue

[Mukto Mona]

I am a newbie in ruby on rails it's also my first ruby application. The
problem is database relation I am trying to make relation within two
tables and the same procedure are working properly in another relation
but here it's showing an error.

The error is:

'undefined method `create_applied_jobs' for nil:NilClass'


Here are my codes:

applied_job.rb

class AppliedJob < ActiveRecord::Base
belongs_to :jobseekers
end

jobseeker.rb

class Jobseeker < ActiveRecord::Base
has_one :applied_job
end

view_details_controller.rb

def create
params.permit!
if @applied_job =
@current_user.create_applied_jobs(params[:applied_job])
flash[:notice] = "You have applied successfully"
render "viewDetails"
else
render "viewDetails"
flash[:warning] = "Please try agian"
end
end

sessions_helper.rb

def current_user
@current_user ||= Jobseeker.find_by(jobseeker_id:
session[:user_id])
end

viewDetails.html.erb

<%= form_for :applied_job, url: viewDetails_path(@applied_job),
action: :create, method: :post do |f| %>
<ul class="form-style-1">
<li><label>Preferred Joining Date<span
class="required">*</span></label>
<%= f.text_field :preffered_joining_date, class:
'field-long', id: 'datepicker', placeholder: 'Preferred Joining Date'%>
</li>
<li>
<label>Expected Salary <span
class="required">*</span></label>
<%= f.text_field :expected_salary, class: 'form-control',
placeholder: 'Expected Salary'%>
</li>
<li>
<input type="submit" value="Submit" />
</li>
</ul>
<% end %>

If you look more carefully at the stack trace (in the server window or
in log/development.log) you should be able to see which line of your
code caused the problem.

I am assuming that it this line that has generated the error. The
error means that you have called create_applied_jobs on a variable
that is nil, so @current_user is nil. Perhaps you have not called
current_user, I don't see where you are calling current_user to set it
up. In fact I am not sure why you don't just have
current_user.create_applied_jobs(params[:applied_job])
though I have not looked in great detail at your code so there may be a reason.

In addition to what Colin has said about setting up @current_user, you
may need to change the method call.

Since this is a has_one relationship rather than has_many, it might
need "create_applied_job" (i.e., singular) instead. (Though it seems
to me you probably want to change the has_one to has_many instead, to
allow seekers to apply to multiple jobs. Possibly even :through some
kind of JobApplication model, where you can store the date, status,
etc.)
