Support querying joined tables from main where clause

Is your feature request related to a problem? Please describe. It would be nice to be able to query joined tables from the main where clause rather than querying the joined tables themselves which may cause the joined tables information to be omitted from the result.

Describe the solution you’d like

Model.findAll({
  include: [ Association1, Association2 ],
  where: { [Op.or]: [
    { 'Association1.ModelId': id },
    { 'Association2.ModelId': id }
  ]}
})

Describe alternatives you’ve considered I’ve considered writing a raw query which is probably what I’ll have to do.

Usage example As I described above I ran into an issue where I needed to join a couple of associations to the model I’m querying but rather than querying each association via include (which may cause some of the associations to not load if certain conditions are or aren’t met) I need a way to query the model and associations.

Note: I have started investigating this. Hopefully I will have time to complete it soon.

I’m not sure I understand this issue, isn’t this already available, but requires surrounding with $ ?

Model.findAll({
  include: [ Association1, Association2 ],
  where: { [Op.or]: [
    { '$Association1.ModelId$': id },
    { '$Association2.ModelId$': id }
  ]}
})
