Json View problem - Could not render / please define a matching clause for render/2 or define a template
I try to render a view as json.
router:
pipeline :api do
plug :accepts, ["json"]
end
scope "/api", MyAppWeb do
pipe_through :api
get "/networking", PageController, :networking
end
controller:
def networking(conn, _params) do
q = from m in Meeting, where: m.is_active == true
meetings = Repo.all(q)
render(conn, "networking.json", meetings: meetings)
end
view:
def render("networking.json", %{meetings: meetings}) do
%{data: render_many(meetings, PageView, "networking.json")}
end
def render("networking.json", %{meeting: meeting}) do
%{id: meeting.id,
title: meeting.title}
end
But I get: Could not render "networking.json for MyAppWeb.PageView, please define a matching clause for render/2 or define a template…
Did I forget something? Thanks for support.

def render("networking.json", %{meetings: meetings}) do
%{data: render_many(meetings, PageView, "networking.json")}
end
def render("networking.json", %{meeting: meeting}) do
%{id: meeting.id,
title: meeting.title}
end
The root key of the second parameter of the function below must match the view’s name.
views/page_view.ex
def render(“networking.json”, %{page: meeting}) do

I guess the problemscan be solved like this:
def render("index.json", %{meetings: meetings}) do
%{data: render_many(meetings, PageView, "networking.json")}
end
def render("networking.json", %{meeting: meeting}) do
%{id: meeting.id,
title: meeting.title}
end
and in controller:
render(conn, "index.json", meetings: meetings)

The plug is here as it is defined in the router in the OP.
I would try to add a catch all clause in the view, just to see what params are sent. Like so…
def render("networking.json", params) do
IO.inspect params
end
