Usage
BEM.Model.decl('fashion-model', {
attributes: {
name: {
type: 'String'
}
}
});
var model = BEM.blocks['fashion-model'].create({
name: 'Kate'
});
model.get('name'); //Kate
Extend
Add declaration for existent one:
BEM.Model.decl('fashion-model', {
attributes: {
sename: {
type: 'String'
}
},
getFullName: function () {
return [this.get('name') + this.get('sename')].join(' ');
}
});
var model = BEM.blocks['fashion-model'].create({
name: 'Kate',
sename: 'Moss'
});
model.getFullName(); //Kate Moss
Inherit:
BEM.Model.decl('uppercased-model', 'fashion-model', {
getFullName: function () {
return this.__base().toUpperCase();
}
});
Nested models and collections
BEM.Model.decl('podium', {
attributes: {
//nested
currentModel: {
type: 'Model',
modelType: 'fashion-model'
},
//collections
avaibleModels: {
type: 'ModelsList',
modelType: 'fashion-model'
}
}
});
Pass models by client id (for browser render only)
//bh template
var model = BEM.blocks['fashion-model'].create();
ctx.content({
block: 'view',
js: {
modelId: model.cid
}
});
//BEM.DOM declaration
var model = BEM.blocks['fashion-model'].getOne(this.params.modelId);
Find models by storage id
var model = BEM.blocks['fashion-model'].getAny(this.params.mongoId);
//load data from storage
model.fetch().done();
Define storage
BEM.Model.decl('fashion-model', {
storage: {
insert: function (model) {
//...
},
update: function (model) {
//...
},
find: function (model) {
//...
},
remove: function (model) {
//...
}
}
});
