    <p>I am currently running into a problem of connecting one model to another. Basically I want a user (user model) to be able to select a specific school (school model) through a form and the user will be under that specific school until they change it. I can't figure out how to exactly go about doing this, any help will be much appreciated! Thank you!</p> <p><strong>user model</strong></p> <pre><code>class User &lt; ActiveRecord::Base attr_accessible :name, :email, :password, :password_confirmation, :biography, :avatar has_secure_password belongs_to :school, foreign_key: "school_id" end </code></pre> <p>I have nothing defined for anything of school in the user model cause I am not sure what to put.</p> <p><strong>school model</strong></p> <pre><code>class School &lt; ActiveRecord::Base attr_accessible :name, :school_id has_many :users validates :school_id, presence: true end </code></pre> <p><strong>user controller</strong></p> <pre><code>def create @user = User.new(params[:user]) if @user.save redirect_to @user else redirect_to current_school end end def update @user = current_user if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated profile." redirect_to home_path else redirect_to current_school end end </code></pre> <p><strong>school controller</strong></p> <pre><code>def create school = School.find(params[:name]) if school session[:school_id] = school.id redirect_to school_path(school) end end def show @school = School.find(params[:id]) @user = User.new end </code></pre> <p><strong>Form for User with school inside</strong></p> <pre><code>&lt;%= simple_form_for @user do |f| %&gt; &lt;%= f.label :Name %&gt;&lt;/br&gt; &lt;%= f.text_field :name, :class =&gt; 'modal_settingfield' %&gt; &lt;/br&gt;&lt;/br&gt; &lt;%= f.label :Email %&gt;&lt;/br&gt; &lt;%= f.text_field :email, :class =&gt; 'modal_settingfield' %&gt; &lt;/br&gt;&lt;/br&gt; &lt;%= f.label :Password %&gt; &lt;span class='faded'&gt;(Leave blank to not change)&lt;/span&gt; &lt;%= f.password_field :password, :class =&gt; 'modal_settingfield'%&gt; &lt;/br&gt;&lt;/br&gt; &lt;%= f.label :Password_Confirmation %&gt; &lt;span class='faded'&gt;(Leave blank to not change)&lt;/span&gt; &lt;%= f.password_field :password_confirmation, :class =&gt; 'modal_settingfield'%&gt; &lt;/br&gt;&lt;/br&gt; &lt;%= f.label :School_id %&gt; &lt;span class='faded'&gt;(Leave blank to not change)&lt;/span&gt; &lt;%= f.association :school, collection: @schools, label_method: :name, value_method: :id, prompt: "Select a school", :label =&gt; false, :required =&gt; false %&gt; &lt;%= f.label :Biography %&gt; &lt;span class='faded'&gt;(Please limit Biography to &lt;span class='TextCounter'&gt;&lt;/span&gt;letters)&lt;/span&gt;&lt;/br&gt; &lt;%= f.text_area :biography, :class =&gt; 'modal_settingfield'%&gt; &lt;/br&gt;&lt;/br&gt; &lt;%= f.label :Photo %&gt; &lt;span class='faded'&gt;(Add a Profile Picture)&lt;/span&gt;&lt;/br&gt; &lt;%= f.file_field :avatar %&gt; &lt;%= f.submit 'Update', :class =&gt; 'update_button' %&gt; &lt;% end %&gt; </code></pre> <p><strong>Current School</strong></p> <pre><code>def current_school @current_school ||= School.find(session[:school_id]) if session[:school_id] end helper_method :current_school </code></pre> <p><strong>Sessions Controller(This is login code)</strong></p> <pre><code>def create user = User.find_by_email(params[:email]) if user &amp;&amp; user.authenticate(params[:password]) if params[:remember_me] cookies.permanent[:auth_token] = user.auth_token else cookies[:auth_token] = user.auth_token end redirect_to home_path else flash.now.alert = "Invalid email or password" redirect_to current_school end end def destroy cookies.delete(:auth_token) redirect_to current_school end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
