Conventions used

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

CodeInText: 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: "For this recipe to work, you will need to have the contenttypes app installed."

A block of code is set as follows:

# requirements/dev.txt
-r _base.txt
coverage
django-debug-toolbar
selenium

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

class Idea(CreationModificationDateBase, MetaTagsBase, UrlBase):
    title = models.CharField(
        _("Title"),
        max_length=200,
    )
    content = models.TextField(
        _("Content"),
    )

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

(env)$ pip install -r requirements/dev.txt

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "We can see here that the upload-related action buttons are also replaced with a Remove button."

Warnings or important notes appear like this.

Tips and tricks appear like this.
