"""
|
||||
Render a form where some specific fields are rendered using Twitter
|
||||
Typeahead and/or splitree's Bootstrap Tokenfield to improve the
|
||||
performance, the speed and UX when dealing with very large datasets
|
||||
(select with 50k+ elts for instance).
|
||||
When the fields specified should normally be rendered as a select with
|
||||
single selectable option, Twitter Typeahead is used for a better display
|
||||
and the matching query engine. When dealing with multiple selectable
|
||||
options, sliptree's Bootstrap Tokenfield in addition with Typeahead.
|
||||
For convenience, it accepts the same parameters as a standard bootstrap
|
||||
can accept.
|
||||
|
||||
**Tag name**::
|
||||
|
||||
massive_bootstrap_form
|
||||
|
||||
**Parameters**:
|
||||
|
||||
form (required)
|
||||
The form that is to be rendered
|
||||
|
||||
mbf_fields (optional)
|
||||
A list of field names (comma separated) that should be rendered
|
||||
with Typeahead/Tokenfield instead of the default bootstrap
|
||||
renderer.
|
||||
If not specified, all fields will be rendered as a normal bootstrap
|
||||
field.
|
||||
|
||||
mbf_param (optional)
|
||||
A dict of parameters for the massive_bootstrap_form tag. The
|
||||
possible parameters are the following.
|
||||
|
||||
choices (optional)
|
||||
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 (optional)
|
||||
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 (optional)
|
||||
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 (optional)
|
||||
A dict of list of ids that the values depends on. The engine
|
||||
and the typeahead properties are recalculated and reapplied.
|
||||
Example :
|
||||
'update_on' : {
|
||||
'field_A' : [ 'id0', 'id1', ... ] ,
|
||||
'field_B' : ... ,
|
||||
...
|
||||
}
|
||||
|
||||
gen_select (optional)
|
||||
A dict of boolean telling if the form should either generate
|
||||
the normal select (set to true) and then use it to generate
|
||||
the possible choices and then remove it or either (set to
|
||||
false) generate the choices variable in this tag and do not
|
||||
send any select.
|
||||
Sending the select before can be usefull to permit the use
|
||||
without any JS enabled but it will execute more code locally
|
||||
for the client so the loading might be slower.
|
||||
If not specified, this variable is set to true for each field
|
||||
Example :
|
||||
'gen_select' : {
|
||||
'field_A': True ,
|
||||
'field_B': ... ,
|
||||
...
|
||||
}
