Hi, guys, I am a rookie in rails, I'd like to make two dynamic selects connecting with the database: in select 1 I have some countries(US,CA,UK) and I already built a table in my database called food: id food_name food_country
the items of select 1 are retrieved from table when selecting a particular item in select 1, select 2 could dynamically change the items it contained(for example, US => 'hamburger', 'chips',.....) furthermore, the two selects are part of one form, when it's submitted, something else like a table or chart will be showed besides the form. I have already read some materials but still struggling in countless trials, I am frustrated by the concepts of render and collect_select(I know little about ajax) and actions interacted in the process, would you like to give me a detailed explanation of the structure to meet with my requirement?
