努力正確實現自定義導軌控制器方法

Question

我試圖實現一個控制器方法，其中一個帳戶向另一個帳戶發送一筆錢。在accnts_controller的代碼如下：

def donate(amt, client) 
    if creator? 
     raise 'Only Patron accounts can donate' 
    else 
     @client = Accnt.find(client) 
     @client.balance += amt 
     @accnt.balance -= amt 
     @client.save 
     @accnt.save 
    end 
    end 

（注：在我的控制，我有一個行動之前它設置了@accnt對象）

要做到這一點，我寫了下面的定製路線：

patch 'accnts/:id/donate' => 'accnts#donate' 

我一直有兩個問題在實施該方法，但遠不是最大的是，我不知道怎麼寫，可以將值傳遞給amt和捲曲請求參數。我幾乎完全使用cURL來測試我的後端的功效，因爲我所在的程序並沒有教會我們如何使用rails視圖。我怎樣才能寫出一個curl請求來測試我的方法？

編輯：我的完整控制器代碼。這是用腳手架生成的，並且被稍微修改

class AccntsController < OpenReadController 
    before_action :set_accnt, only: %i[show update donate destroy] 
    # GET /accnts 
    def index 
    @accnts = Accnt.all 
    render json: @accnts 
    end 
    # GET /accnts/1 
    def show 
    render json: @accnt 
    end 
    # POST /accnts 
    def create 
    if current_user.accnt 
     raise 'Already has an account' 
    else 
     @accnt = Accnt.new(accnt_params) 
     @accnt.user = current_user 
     if @accnt.save 
     render json: @accnt, status: :created 
     else 
     render json: @accnt.errors, status: :unprocessable_entity 
     end 
     # render json: @accnt, status: :created, location: @accnt if @accnt.save 
    end 
    end 
    # PATCH/PUT /accnts/1 
    def update 
    if @accnt.update(accnt_params) 
     render json: @accnt 
    else 
     render json: @accnt.errors, status: :unprocessable_entity 
    end 
    end 
    # amt is the amount to be sent from the patron to the client, client is the client ID 
    def donate(amt, client) 
    # furthermore, I cannot say for certain whether this method of passing parameters is viable in rails 
    if creator? 
     raise 'Only Patron accounts can donate' 
    else 
     # Very easily could be logical errors here 
     @client = Accnt.find(client) 
     @client.balance += amt 
     @accnt.balance -= amt 
     @client.save 
     @accnt.save 
    end 
    end 
    # DELETE /accnts/1 
    def destroy 
    @accnt.destroy 
    end 
    private 
    # Use callbacks to share common setup or constraints between actions. 
    # To be used as a before method to determine whether or not the account in 
    # question is a creator account 
    def creator? 
     creator 
    end 
    def set_accnt 
     @accnt = Accnt.find(params[:id]) 
    end 
    # Only allow a trusted parameter "white list" through. 
    def accnt_params 
     params.require(:accnt).permit(:user_id, :user_name, :balance, :creator, :content_type, :content_list) 
    end 
end 

對於捲曲的要求，我還沒有真正寫出來超出了：

API="http://localhost:4741" 
URL_PATH="/accnts" 
curl "${API}${URL_PATH}/${ID}/donate" \ 
    --include \ 
    --request PATCH \ 
    --header "Content-Type: application/json" \ 
    --header "Authorization: Token token=$TOKEN" \ 
    --data 
echo

以下是工作方法的代碼和捲曲請求N3我的控制器：

def donate 
    if @accnt.creator 
    raise 'Only Patron accounts can donate' 
    else 
    client = params[:client_id] 
    amt = params[:amt] 
    # Very easily could be logical errors here 
    @client = Accnt.find(client) 
    @client.balance += amt 
    @accnt.balance -= amt 
    @client.save 
    @accnt.save 
    end 
end 

和我（令人髮指的硬編碼）捲曲要求：

API="http://localhost:4741" 
URL_PATH="/accnts" 
ID="2" 
TOKEN="BAhJIiU2ZDA2MGI4YzZkZjFkMmRkYTBkMWI3ZmRjMmRiMTZlYgY6BkVG--e55aee8e39c0cdd0bf944fa66661f06930037ba1" 
curl "${API}${URL_PATH}/${ID}/donate" \ 
    --include \ 
    --request PATCH \ 
    --header "Content-Type: application/json" \ 
    --header "Authorization: Token token=$TOKEN" \ 
    --data '{ 
    "client_id": 1, 
    "amt": 10.0 
    }' 
echo
