rater | highly customizable rating widget that supports images | Plugin library

You can use uniqueness validation for a column in scope of other column. Here is the example that can help you.

validates :name, presence: true, uniqueness: { scope: :position }

OR

validates :name, uniqueness: { scope: :position }

*(In case the name field is not mandatory).

If the position is association then user position_id the foreign key with the scope.

ex: { scope: :position_id }.

I think you want to really do this in 2 steps,..

First make a function to get the root node your looking for, and then you can just use map like normal.

Below is an example.

You can wrap your code in a function and then lapply over the hdf path. In this way if your loop is too slow it will be easy to parallelize it. You could try this:

It would be easier if you get the data in long format.

You first need to append your content inside ul tag then use $("#user_list li:last .rating").rate({//your option}) to initialize your rater plugin with rating value.

Demo Code :

The skipping frames likely has nothing to do with the code you posted: it sounds like a misconfiguration of RecyclerViews / Adapters to me. You'll need to post that code for it be more clear though.

However, even though what you posted likely isn't the culprit you can still optimize the coroutines code you have:

The assumption is that in your scenario a user can rate other users, and they (themselves) can be rated. Basically, there is one table called User referencing other users within an application.

A relationship in which instances of a class are linked to other instances of the same class is called self-referential relationship, and that is exactly what you have here.

Here is a diagram that represents this self-referential many-to-many relationship that keeps track of ratings:

The Ratings table is the association table of the relationship. The foreign keys in this table are pointing at entries in the User table since it is linking users to users.

To add this table to your database, this is how you can go about it:

The labels on the axes should correspond to names(dimnames(ctable)), so try changing those.

To have more space it might help if you increase the size of your output device, since font sizes are hard-coded in the agreementplot function you linked to. So if you output to png, try increasing width and height, for example. If you are using RStudio, you can change the size of the plot window and/or the export preview window to see how that affects the relative sizes and whether that can give you something you are happy with.

Alternatively, you could modify the agreementplot function if you want to adjust some of the hard-coded values, such as font sizes and offset of axis labels. It might help if you rotated the labels using e.g. ylab_rot = 0, ylab_just = "right" (which you could do without modifying the function), but you also may have to change the x value in the line grid.text(ylab, x = -0.1, gp = gpar(fontsize = 20), rot = 90) to something smaller (e.g. 0.3, depending on your labels to make it look decent).
