I'm unable to figure out how to construct a graphql query for performing the mongodb fulltext search using the text index. https://docs.mongodb.com/manual/text-search/
I've already created a text index on my string in the mongoose schema but I don't see anything in the schemas that show up in the grapqhl playground.
A bit late, though I was able to implement it like so
const FacilitySchema: Schema = new Schema(
{
name: { type: String, required: true, maxlength: 50, text: true },
short_description: { type: String, required: true, maxlength: 150, text: true },
description: { type: String, maxlength: 1000 },
location: { type: LocationSchema, required: true },
},
{
timestamps: true,
}
);
FacilitySchema.index(
{
name: 'text',
short_description: 'text',
'category.name': 'text',
'location.address': 'text',
'location.city': 'text',
'location.state': 'text',
'location.country': 'text',
},
{
name: 'FacilitiesTextIndex',
default_language: 'english',
weights: {
name: 10,
short_description: 5,
// rest fields get weight equals to 1
},
}
);
After creating your ObjectTypeComposer for the model, add this
const paginationResolver = FacilityTC.getResolver('pagination').addFilterArg({
name: 'search',
type: 'String',
query: (query, value, resolveParams) => {
resolveParams.args.sort = {
score: { $meta: 'textScore' },
};
query.$text = { $search: value, $language: 'en' };
resolveParams.projection.score = { $meta: 'textScore' };
},
});
FacilityTC.setResolver('pagination', paginationResolver);
Then you can assign like so
const schemaComposer = new SchemaComposer();
schemaComposer.Query.addFields({
// ...
facilities: Facility.getResolver('pagination')
// ...
});
On your client side, perform the query like so
{
facilities(filter: { search: "akure" }) {
count
items {
name
}
}
}
I have an array of 20 objects which I am getting from a database, each of them has an unique id. I also have an array of data with 2 ids. I want want to filter out only those 2 objects from the array of 20.
computed: {
newHeros(){
return this.getAllHeros.filter(newHero => {
console.log(newHero.id);
return newHero.id === this.heroForTab
})
}
},
return {
heroForTab: ['76NQjrYTdfbWN8xZOAvI', 'uDsm0BValBa31guJs10h']
};
User Array.filter to return what you need
var heroForTab = ['76NQjrYTdfbWN8xZOAvI', 'uDsm0BValBa31guJs10h'];
var arr = [{
id: '76NQjrYTdfbWN8xZOAvI',
name: 'aaa'
},
{
id: '1111',
name: 'bbb'
},
{
id: '2222',
name: 'ccc'
},
{
id: 'uDsm0BValBa31guJs10h',
name: 'ddd'
}
]
var result = arr.filter(item => {
return heroForTab.includes(item.id)
})
console.log(result)
What I have is an object like this:
formData = {
name: {
value: '',
valid: true
},
zip: {
value: 'ff',
valid: false
},
//...
}
And I want to filter this so that I only have the invalid objects. The problem with _.where and _.filter is that it returns an object like this:
[
0: {
value: '',
valid: false
},
1: {
value: '',
valid: false
}
]
I need the parent key names, name and zip to be included. How do I do this?
You are looking for _.pick() my friend.
https://lodash.com/docs#pick
_.pick(formData, function(value) {
return value.valid;
})
Good luck! :)
I am learning DOJO 1.6.
I have data
var data = [
{ FirstName: 'xyz', Lastname: 'QSD', rollNo: '1', EntryDate: '2012-09-11T17:35:31.835+02:00' },
{ FirstName: 'abc', Lastname: 'qgr', rollNo: '2', EntryDate: '2012-08-11T17:35:31.835+02:00' }
{ FirstName: 'ert', Lastname: 'fgd', rollNo: '3', EntryDate: '2012-18-11T17:35:31.835+02:00' }
];
I want to sort it with respect to Last name or EntryDate and display in a tree format.
Thanks in Advance.
Multiple root data
data: [
{ id: 'world', name:'The earth', type:'planet', population: '6 billion'},
{ id: 'AF', name:'Africa', type:'continent', population:'900 million', area: '30,221,532 sq km',
timezone: '-1 UTC to +4 UTC', parent: 'world'},
{ id: 'EG', name:'Egypt', type:'country', parent: 'AF' },
{ id: 'KE', name:'Kenya', type:'country', parent: 'AF' },
{ id: 'Nairobi', name:'Nairobi', type:'city', parent: 'KE' },
{ id: 'Mombasa', name:'Mombasa', type:'city', parent: 'KE' },
{ id: 'SD', name:'Sudan', type:'country', parent: 'AF' },
{ id: 'Khartoum', name:'Khartoum', type:'city', parent: 'SD' },
{ id: 'AS', name:'Asia', type:'continent', parent: 'world' },
{ id: 'CN', name:'China', type:'country', parent: 'AS' },
{ id: 'IN', name:'India', type:'country', parent: 'AS' },
{ id: 'RU', name:'Russia', type:'country', parent: 'AS' },
{ id: 'MN', name:'Mongolia', type:'country', parent: 'AS' },
{ id: 'OC', name:'Oceania', type:'continent', population:'21 million', parent: 'world'},
{ id: 'EU', name:'Europe', type:'continent', parent: 'world' },
{ id: 'DE', name:'Germany', type:'country', parent: 'EU' },
{ id: 'FR', name:'France', type:'country', parent: 'EU' },
{ id: 'ES', name:'Spain', type:'country', parent: 'EU' },
{ id: 'IT', name:'Italy', type:'country', parent: 'EU' },
{ id: 'NA', name:'North America', type:'continent', parent: 'world' },
{ id: 'SA', name:'South America', type:'continent', parent: 'world' }
],
Javascript Array has a native function, called sort. This will off-the-shelf sort the values alphabetically. For the purpose of sorting non-string-values, we need to supply a sortingfunction. Like so, in regards to Lastname:
data.sort(function(a,b) {
var _A=a.Lastname.toLowerCase(),
_B=b.Lastname.toLowerCase();
if (_A < _B) //sort string ascending
return -1
if (_A > _B)
return 1
return 0 //default return value (no sorting)
});
If youre sorting against a date, you would need to initialize _A and _B to a Date.
However, if youre aiming to represent the data in a dijit.Tree, there's inbuilt method for sorting the Store, lets wrap data into a dojo/data/ItemFileReadStore and show in a tree. Tree will have a model, using ItemFileWriteStore - so that items can be modified:
var sortableStore = new dojo.data.ItemFileReadStore({
data: {
identifier: 'rollNo',
items: data
},
comperatorMap: {
'EntryDate' : function(a,b) {
var _A = new Date(a), _B = new Date(b);
if(_A > _B) return 1;
else if(_A == _B) return 0;
else return -1;
}
});
Using 'store.fetch()' API while setting the 'sort' parameter, you control the order of returned items. The EntryDate you will have to create a comperatorMap of functions, as with Array.sort() in order to sort it properly. See the documentation.
var model = new dijit.tree.ForestStoreModel({
rootLabel: 'Names',
store: new dojo.data.ItemFileWriteStore({
data: {
identifier: 'rollNo',
items: data,
// blank, initially - can fill in with 'data' to show non-sorted items until sort is called
label: 'FirstName'
}
}) // blank itemsstore
});
var tree = new dijit.Tree({
model: model
});
OK, All set - but problem with .fetch is, it runs with callbacks (onComplete) and is difficult to control in a recursive manner. Instead, the functionality put in THIS FIDDLE duplicates the store data and then sorts it via native array sort - as opposed to using SimpleQueryEngine.
This will prove to give more reliable results - but does mess with DnD controllers and persist flag..
See how store can sort its items returned by fetch here: fiddle. This however only sorts one 'level' at a time and does not perform deep sorts.
IMO: The proper implementation of sort is a serverside sort, directly in the database query.

I have created classes
dojo.declare("UNIT",null,{
_id:'',
constructor:function(i){
this._id=i;
});
and
dojo.declare("ELEMENT", null, {
_id:'',
_unit_id:'',
constructor:function(u,i){
this._unit_id=u;
this._id=i;
});
I have array of Units and I want find one which have id like my element._unit_id. Hot to do this with Dojo ? I was looking in documentation examples but there is dojo.filter by I cannot pass argument . Can anybody help ?
You can use dojo.filter.E.g:
var units = [{
id: 1,
name: "aaaa"
},
{
id: 2,
name: "bbbb"
},
{
id: "2",
name: "cccc"
},
{
id: "3",
name: "dddd"
}];
var currentElementId = 2;
var filteredArr = dojo.filter(units, function(item) {
return item.id==currentElementId;
});
// do something with filtered array
}
