@ -50,34 +50,97 @@ def bootstrap_form_typeahead(django_form, typeahead_fields, *args, **kwargs):
A list of field names (comma separated) that should be rendered
with typeahead instead of the default bootstrap renderer.
choices
A string representing the choices in JS. The choices must be an
array of objects. Each of those objects must at least have the
fields 'key' (value to send) and 'value' (value to display).
Other fields can be added as desired.
If not specified, the key is the id of the object and the value
is its string representation as in a normal bootstrap form.
Example :
choices='[{key:0,value:"choice0",extrafield:"data0"}, {...},...];'
bft_param
A dict of parameters for the bootstrap_form_typeahead tag. The
possible parameters are the following.
match_func
A string representing a valid JS function used in the dataset to
overload the matching engine. This function is used the source of
the dataset. This function receives 2 parameters, the query and
the synchronize function as specified in typeahead.js documentation.
If needed, the local variables 'choices' and 'engine' contains
respectively the array of possible values and the engine to match
queries with possible values.
If not specified, the function used display up to the 10 first
elements if the query is empty and else the matching results.
Example :
match_func='function(q, sync) { engine.search(q, sync); }'
choices
A dict of strings representing the choices in JS. The keys of
the dict are the names of the concerned fields. The choices
must be an array of objects. Each of those objects must at
least have the fields 'key' (value to send) and 'value' (value
to display). Other fields can be added as desired.
For a more complex structure you should also consider
reimplementing the engine and the match_func.
If not specified, the key is the id of the object and the value
is its string representation as in a normal bootstrap form.
Example :
'choices' : {
'field_A':'[{key:0,value:"choice0",extra:"data0"},{...},...]',
'field_B':...,
...
}
engine
A dict of strings representating the engine used for matching
queries and possible values with typeahead. The keys of the
dict are the names of the concerned fields. The string is valid
JS code.
If not specified, BloodHound with relevant basic properties is
used.
Example :
'engine' : {'field_A': 'new Bloodhound()', 'field_B': ..., ...}
match_func
A dict of strings representing a valid JS function used in the
dataset to overload the matching engine. The keys of the dict
are the names of the concerned fields. This function is used
the source of the dataset. This function receives 2 parameters,
the query and the synchronize function as specified in
typeahead.js documentation. If needed, the local variables
'choices_<fieldname>' and 'engine_<fieldname>' contains
respectively the array of all possible values and the engine
to match queries with possible values.
If not specified, the function used display up to the 10 first
elements if the query is empty and else the matching results.
Example :
'match_func' : {
'field_A': 'function(q, sync) { engine.search(q, sync); }',
'field_B': ...,
...
}
update_on
A dict of list of ids that the values depends on. The engine
and the typeahead properties are recalculated and reapplied.
Example :
'addition' : {
'field_A' : [ 'id0', 'id1', ... ] ,
'field_B' : ... ,
...
}
See boostrap_form_ for other arguments
**Usage**::
{% bootstrap_form_typeahead form ['field1[,field2[,...]]] %}
{% bootstrap_form_typeahead
form
[ '<field1>[,<field2>[,...]]' ]
[ {
[ 'choices': {
[ '<field1>': '<choices1>'
[, '<field2>': '<choices2>'
[, ... ] ] ]
} ]
[, 'engine': {
[ '<field1>': '<engine1>'
[, '<field2>': '<engine2>'
[, ... ] ] ]
} ]
[, 'match_func': {
[ '<field1>': '<match_func1>'
[, '<field2>': '<match_func2>'
[, ... ] ] ]
} ]
[, 'update_on': {
[ '<field1>': '<update_on1>'
[, '<field2>': '<update_on2>'
[, ... ] ] ]
} ]
} ]
[ <standard boostrap_form parameters> ]
