Find in array (whereEqualOR) #116

Closed proft closed 8 years ago

proft commented 8 years ago

Hello!

Can I find documents by any value in array, for example in JS

const tags = ["tag1", "tag2"];
Messages.find({entity: entity, tag: {$in: tags}}, {sort: {created: 1}})

If I use whereEqual

Document[] documents = db.getCollection("Messages").whereEqual("tag", "tag1").whereEqual("tag", "tag2").whereEqual("entity", entityID).find();

then it filter all documents with tag = "tag1" AND then with tag = "tag2".

I want whereEqualOR() or whereInArray(field, array) :)

We'll add the following:

Query whereIn(String fieldName, Object[] fieldValues);

Thanks a lot for this suggestion -- it's indeed an important addition!

Any date release? :)

PS: anyway thank you for this marvellous lib!

Today :)

The two new operators whereIn and whereNotIn should have been implemented in https://github.com/delight-im/Android-DDP/commit/103a8927d3620a4696a417a5ae8c193041f1767d now.

Can you try replacing the version v3.1.2 in your Gradle dependency with the following commit hash, please?

Feedback would be much appreciated. Thanks!

Documentation in the README will be updated if this has been confirmed to work. Use arrays as value lists with these operators:

new String[] { "abc", "def", "ghi" }
// or
new Integer[] { 1, 2, 3 }
// or
// ...

Works like a charm. I had one strange error about can't find interface ... but after Clean Project it works as I expect. Tested on two projects in different situations. It works! :) Thank you!
