The RESTful convention has been invaluable regarding creating a consistency in the internet allowing for improved communication. However, as with most things in life, there are exceptions. My project involved having a page on which people can enter their medical histories and subjective reports. It would not be convenient for the user to enter part of the information on one page and then to proceed to the next page. This is separate from notes which a person may or may not make use of and therefore is appropriate to put on a separate page.

This is the page being discussed:

The issue with this arrangement regarding the history and subjective areas is that they come from two separate tables. Therefore, the name on the route cannot be RESTful and simply use the name of the table since we have two tables represented on the page.
The schema is as follows:

create_table "comments", force: :cascade do |t|
t.text "identifier"
t.text "note"
t.text "items_to_discuss"
t.text "questions"
t.integer "patient_id"
end

create_table "histories", force: :cascade do |t|
t.text "diagnoses"
t.text "medications"
t.text "allergies"
t.text "current_treatments"
t.text "surgeries"
t.text "immunizations_with_dates"
t.integer "patient_id"
end

create_table "patients", force: :cascade do |t|
t.string "username"
t.string "password_digest"
end

create_table "subjectives", force: :cascade do |t|
t.text "location"
t.text "observed_changes"
t.text "sensation_changes"
t.string "scale_1_to_10"
t.text "length_of_time"
t.integer "patient_id"
end

end

This is the code for the page being discussed. As you can see, the two tables have their respective information entered separately even though two tables are being updated:

Finally, the following code allows for the saving of information for both sections from the same page:

post '/patients/:id/info' do
redirect_if_not_logged_in
patient = Patient.find(session["patient_id"])
history = History.new(:diagnoses => params[:histories][:diagnoses])
history.medications = params[:histories][:medications]
history.allergies = params[:histories][:allergies]
history.current_treatments = params[:histories][:current_treatments]
history.surgeries = params[:histories][:surgeries]
history.immunizations_with_dates = params[:histories][:immunizations_with_dates]
history.patient_id = patient.id
history.save
subjective = Subjective.create(:location => params[:subjectives][:location])
subjective.observed_changes = params[:subjectives][:observed_changes]
subjective.sensation_changes = params[:subjectives][:sensation_changes]
subjective.scale_1_to_10 = params[:subjectives][:scale_1_to_10]
subjective.length_of_time = params[:subjectives][:length_of_time]
subjective.patient_id = patient.id
subjective.save

    redirect 'patients/:id/info'
end

As is evident from the above code, the route ends with /info which is not a RESTful term as /show would be. However, it does convey the meaning of what is presented on the page.

In conclusion, RESTful convention should indeed be used as frequently as possible. This presentation gives an example where being non-RESTful can be justified.
