    <p>I receive a noMethodError when attempting to utilize a method in my application_helper file.</p> <p>It looks like the helper method itself is fine, but the code inside the helper method is whats triggering the error. I have double checked my model and schema files to be certain that I had the attributes listed correctly. A fresh pair of eyes on this would be well received.</p> <p>Here's my code...</p> <p>application_helper.rb</p> <p>PS. I'm showing both sets of helper methods here because this first set (Resident Helper Methods) works fine in the views it was intended for.</p> <pre><code> # START -- Resident Helper Methods def resident_full_name ([@resident.fname, @resident.lname] - [ '' ]).compact.join(' ') end def resident_dob @resident.dob end def resident_gender @resident.gender end def resident_doc_full_name ([@resident.doc_fname, @resident.doc_lname] - [ '' ]).compact.join(' ') end def resident_doc_phone1 @resident.doc_phone1 end def resident_doc_address @resident.doc_address end def resident_doc_city @resident.doc_city end def resident_doc_state @resident.doc_state end def resident_doc_zip @resident.doc_zip end def resident_guard_full_name @resident.guard_full_name end def resident_guard_phone @resident.guard_phone end def resident_desrep_full_name @resident.desrep_full_name end def resident_desrep_phone @resident.desrep_phone end # END -- Resident Helper Methods # START -- User Helper Methods def user_full_name ([@user.fname, @user.lname] - [ '' ]).compact.join(' ') end # END -- User Helper Methods # START -- User Helper Methods def user_full_name @user_full_name = ([@user.fname, @user.lname] - [ '' ]).compact.join(' ') return @user_full_name end # END -- User Helper Methods # START -- Admin Helper Methods def fac_owner_full_name @fac_owner_full_name = ([@admin.owner_fname, @admin.owner_lname] - [ '' ]).compact.join(' ') return @fac_owner_full_name end def fac_name @fac_name = @admin.fac_name return @fac_name end def fac_lic_num @fac_lic_num = @admin.lic_num return @fac_lic_num end def fac_address @fac_address = @admin.fac_address return @fac_address end def fac_state @fac_state = @admin.fac_state return @fac_state end def fac_zip @fac_zip = @admin.fac_zip return @fac_zip end def fac_email @fac_email = @admin.fac_email1 return @fac_email end def fac_phone @fac_phone = @admin.fac_phone1 return @fac_phone end # END -- Admin Helper Methods </code></pre> <p>show.html.erb</p> <pre><code>&lt;tr&gt;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
