Hello, I have two models in Grid. One with a foreign key. What I want to do is combine the values of a field from the first pattern in a column and a field from the model with a foreign key into one arm. In other words, if the value is "A" in the relevant column in the first model, and the value is "B" in the model with a foreign key, it will appear as "AB" in this column. How can I do?
