There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Be sure to also include this app in your INSTALLED_APPS variable found in the settings.py file."

A block of code is set as follows:

# /becoming_a_django_entdev/chapter_5/forms.py
from django.forms 
import Form
class ContactForm(Form):
    pass

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

# /becoming_a_django_entdev/chapter_5/forms.py
from django.forms 
import Form, ModelForm
class VehicleForm(ModelForm):
    pass

Any command-line input or output is written as follows:

RuntimeError: Conflicting 'vehicle' models in application 'chapter_3':

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: " We can see the chapter_3_engine and chapter_3_practice_engine tables in the preceding screenshot."
