Ruby Sinatra Help

I need help with Function 1, 3, and 4 (I covered them in pound signs so its easier for you to see. I also left comments about what the request should do.).

I left my code to show that I was trying.

I believe the post request is correct. (Function 2, if you will)

The code is in two separate images because it did not fit.

I will paste the instruction of this assignment below.

Part 1 Instructions

1. Make requests to GET /dogs display a line for each dog in the database with the following format: id: name - breed - weight
2. Make requests to POST /dogs create a new dog where the name, breed, and weight of the dog to be created are grabbed from parameters name, breed, and weight respectively.
3. Make requests to PATCH /dogs update the information for an existing dog, when given new information (from the parameters) and the id of the dog to update (from the parameters).
4. Make requests to DELETE /dogs delete an existing dog from the database (if it exists) when given the id of the dog to delete.

Part 2 Instructions

1. Make sure POST requests to /dogs don't make a new dog unless the name, breed, and weight parameters are all set.
2. Make sure PATCH requests to /dogs work as long as the parameter id is provided and at least one other parameter (name, breed, or weight).
3. Make sure DELETE requests to /dogs don't delete anything if the parameter id is not specified or the dog is not found in the database.

Thank you so so much!
