I am new to javascript and very new to Meteor. Is this code correct? I need to define a function which will take an array of values and insert them in a Meteor Collection "FooterButtons"?
Client code
replaceCollectionContents(['NO', 'B', 'YES']);
Both code
replaceCollectionContents = function (buttonsList) {
FooterButtons.remove();
for(i = 0; i < buttonsList.length; i++) {
FooterButtons.insert(buttonsList[i]);
}
};
You cannot directly insert a string to a collection. The insert method expects a document which is of type object.
Try this instead -
FooterButtons.insert({ text: buttonsList[i] });
Also, I notice that you are trying to clear your FooterButtons collection. Please note that you cannot clear a collection like this from the client side as it is considered untrusted code. From client side, you can only remove one document at a time, specified by its _id.
I would recommend you to use a method instead.
Meteor.methods({
replaceCollectionContents: function (buttonsList) {
// remove all existing documents in the collection
FooterButtons.remove({});
// insert new button documents into the collection
buttonsList.forEach(function (button) {
FooterButtons.insert({ text: button });
});
}
});
And call this method when needed
Meteor.call("replaceCollectionContents", ['NO', 'B', 'YES']);
Inside the method, note that I'm passing a {} selector to the remove method because for safety reasons, Meteor does not remove any documents if selector is omitted.
You can read more about remove in Meteor docs.
If I understand correctly, you need to seed data into FooterButtons collection, correct?
Put this code somewhere on your server folder:
buttonsList = ['NO', 'B', 'YES'];
if (FooterButtons.find().count() === 0) {
_.each(buttonsList, function(button) {
FooterButtons.insert({text: button});
});
}
Run meteor and check your mongodb FooterButtons collection. Let me know. I'll make explanation if this work
If you need to update, then update it:
FooterButtons.update({text:'B'}, {$set:{text:'Extra'}});
