Rails
1

I am new to rails, And stuck in this problem from last two days I have a
student and student_parent model they have a one-to-many relationship
i
want to build database attribute through one object from form to
datase.

controller’s method

def new@student = Student.new1.times{ @student.student_parents.build
}…

end

Create Method:-

def create
@student = Student.new(params[:student])
respond_to do |format|
if @student.save
format.html { redirect_to Student, notice: ‘Student was successfully
created.’ }
format.json { render json: @student, status: :created, location:
@student
}
else
format.html { render action: “new” }
format.json { render json: @student.errors, status:
:unprocessable_entity
}
end
end

Model:- class Student < ActiveRecord::Base
belongs_to :user has_many :student_parents
attr_accessible :birth_date, :blood_group, :first_name, :gender,
:last_name, :middle_name, :school_name, :student_rollno, :email,
:user_id,
:student_parents_attributes
accepts_nested_attributes_for :student_parents end

form:-

<%= simple_form_for @student, :html => { :class => ‘form-horizontal’ }
do |f| %>

<%= f.label :first_name, :class => 'control-label',:required => true %> <%= f.text_field :first_name %>
<%= f.label :middle_name, :class => 'control-label'%> <%= f.text_field :middle_name %>
<%= f.label :last_name, :class => 'control-label',:required => true %> <%= f.text_field :last_name %>
 
Email
<%= f.text_field :email, :class => 'text_field' %>
Birth Date *
<%= f.text_field :birth_date, :class => 'text_field' ,'data-behaviour' => 'datepicker' %>
<% model_class = StudentParent %>

Parent Information

<%= f.fields_for :student_parents do |student_parent| %> 
<!--<div class="span9">-->

   <h5> Father Name </h5>

   <div class="span3">
      <%= student_parent.label :first_name, :class =>

‘control-label’,:required => true %>
<%= student_parent.text_field :first_name %>

   <div class="span3">
      <%= student_parent.label :middle_name, :class =>

‘control-label’%>
<%= student_parent.text_field :middle_name %>

   <div class="span3">
      <%= student_parent.label :last_name, :class =>

‘control-label’,:required => true %>
<%= student_parent.text_field :last_name %>

  
<div class="row-fluid">

  <h5> Mother Name </h5>

  <div class="span3">
    <%= student_parent.label :first_name, :class =>

‘control-label’,:required => true %>
<%= student_parent.text_field :first_name %>

  <div class="span3">
    <%= student_parent.label :middle_name, :class =>

‘control-label’%>
<%= student_parent.text_field :middle_name %>

  <div class="span3">
    <%= student_parent.label :last_name, :class =>

‘control-label’,:required => true %>
<%= student_parent.text_field :last_name %>

</div> &nbsp;

<% end %>

<%= f.button :submit, :class => 'btn-primary' %> <%= link_to t('.cancel', :default => t("helpers.links.cancel")), students_path, :class => 'btn' %>

when submit it only build student information in student table and
mother
information in student_parent table. But it miss the parent
information.

I want to submit student entry in student table & Father and mother
entry
simultaneously in student_parents table.

Hi Tushar,

Your controller does not have to only speak to the Student model. You
could
have it also create the StudentParent entries from the information you
got
submitted by the form. Once you verify that the Student object and the
StudentParent object saved successfully you would return true. A failure
in
either you would return false with the error that caused the failure.

Thanks,
