How to add members to a project?

Question

Ruby on Rails

Hello everyone) There is a table of participants (participant.rb) and teams (team.rb) I want to make it so that when creating a team, a list of participants appears and each of them can be added to the team. Here are the links of the models.
class < ActiveRecord::Base
has_many :participant_teams
has_many :teams, through: :participant_teams
end
class Team < ActiveRecord::Base
has_many :participant_teams
has_many :participants, through: :participant_teams
end
class ParticipantTeam < ActiveRecord::Base
belongs_to :team
belongs_to : participant
end
Let's say I created a team and went to the team page. On the team page there is a button to add members, when clicked, a list of members appears in a modal window. And under each participant there is a button to add him to the team.
class TeamsController < ApplicationController
def participant_collection
@participants = Participant.all
respond_to do |format| // returns all members in js format on the teams/1
page format.js {}
end
end
end
How do I write a method that will add members to a team? Share your knowledge, experience. Maybe there is another way to do it. Thank you all in advance.)
