how to add filter dynamic?

[Matrix-Zhang]

i want to select rows with much filters.

how to write the code ? because of the rust static type system, i don't know the right type of the filter

like posts.eq(1).or(posts.between(5..8))

Can you give the full code that you're trying to write? Is posts an integer column?

[Matrix-Zhang]

posts is integer, the sever will recive the user input as filter, su as "1,2,5-8"
so, i need build the filter from the user's input

http://docs.diesel.rs/diesel/prelude/trait.BoxedDsl.html will help you dynamically build the query. As for parsing the string, that's not something Diesel can help with.
