I am trying to build a kind of specific simple schema for a collection and i would like to make sure that :
when the user enter a new select in my selectsCollection, he will put one of the options value as selected value.
For example:
SelectsCollection.insert({name:"SelectOne",deviceType:"Select",options:["option1","option2","option3"],value:"option4",description:"This is the first select"});
this do not have to work. I want him to write only one of the 3 options.
Here my schema :
SelectsCollection = new Mongo.Collection('Selects'); //Create a table
SelectsSchema = new SimpleSchema({
name:{
type: String,
label:"Name",
unique:true
},
deviceType:{
type: String,
allowedValues: ['Select'],
label:"Type of Device"
},
options:{
type: [String],
minCount:2,
maxcount:5,
label:"Select Values"
},
value:{
type: String,
//allowedValues:[options] a kind of syntax
// or allowedValues:function(){ // some instructions to retrieve the array of string of the option field ?}
label:"Selected Value"
},
description:{
type: String,
label:"Description"
},
createdAt:{
type: Date,
label:"Created At",
autoValue: function(){
return new Date()
}
}
});
SelectsCollection.attachSchema(SelectsSchema);
Any Idea ? :)
Thanks a lot !
This could be done with custom
validation function of a field, inside this function you could retrieve values from other fields:
SelectsSchema = new SimpleSchema({
// ...
options: {
type: [String],
minCount: 2,
maxcount: 5,
label: "Select Values"
},
value: {
label: "Selected Value",
type: String,
optional: true,
custom() {
const options = this.field('options').value
const value = this.value
if (!value) {
return 'required'
}
if (options.indexOf(value) === -1) {
return 'notAllowed'
}
}
},
// ...
});
