class HTMLBuilder():
|
||
|
|
"""
|
||
|
|
Assembles HTML response through substitution according to the passed dictionary.
|
||
|
|
The keys need to be in curly braces inside one of the passed files.
|
||
|
|
|
||
|
|
The list of files gets glued together in the order they are in, so a head.html
|
||
|
|
would need to be the first element.
|
||
|
|
|
||
|
|
Can be used to glue files without substitution by not passing data dictionary.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
sub_dict = {
|
||
|
|
"page_title": {
|
||
|
|
"type": "item",
|
||
|
|
"value": "My Booklist!"
|
||
|
|
},
|
||
|
|
"books": {
|
||
|
|
"type": "list",
|
||
|
|
"value": ["Book1", "Book2"]
|
||
|
|
},
|
||
|
|
"select": {
|
||
|
|
"type": "radio",
|
||
|
|
"value": ["Book1", "Book2"]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
response = HTMLBuilder(["html/head.html", "html/home.html"], sub_dict).build()
|
||
|
|
|
||
|
|
:param list files: the files that are glued together in order
|

|

:param dict data: the dictionary with which placeholders get replaced
