I’m trying to implement multiple file upload buttons inside the same live_view. I have this kind of code:
defmodule AlbumWeb.AlbumLive do
use AlbumWeb, :live_view
alias Album.HashedIds
alias Integer
require Logger
def mount(%{"id" => id}, _session, socket) do
album_id = HashedIds.decode!(id)
album = Album.get_album!(album_id)
pages_per_album = Application.get_env(:album, :pages_per_album, 10)
{:ok, assign(socket, album: album, pages_per_album: pages_per_album)}
end
def render(assigns) do
~H"""
<div class="flex-1 book_holder">
<div class="book" style="--c: 0;--translate: 0;">
<%= for page <- 0..(@pages_per_album - 1) do %>
<PageComponents.photo_page page={page}>
<:front>
<.live_component
module={AlbumWeb.PhotosetLive}
id={page * 2}
page={page * 2}
album={@album}
/>
</:front>
<:back>
<.live_component
module={AlbumWeb.PhotosetLive}
id={page * 2 + 1}
page={page * 2 + 1}
album={@album}
/>
</:back>
</PageComponents.photo_page>
<% end %>
</div>
</div>
"""
end
end
which uses AlbumWeb.PhotosetLive a few times. PhotosetLive is defined like so
defmodule AlbumWeb.PhotosetLive do
use AlbumWeb, :live_component
# use def update_many(assigns_sockets) to load all photos in the albnum
def mount(socket) do
socket =
socket
|> assign(:uploaded_files, [])
|> allow_upload(:photoset, accept: ~w(.jpg .jpeg .png .webp), max_entries: 7)
{:ok, socket}
end
def handle_event("validate", _params, socket) do
{:noreply, socket}
end
def handle_event("save", _params, socket) do
uploaded_files =
consume_uploaded_entries(socket, :photoset, fn %{path: path}, _entry ->
dest = Path.join("priv/static/uploads", Path.basename(path))
IO.puts(path <> " -> " <> dest)
end)
{:noreply, update(socket, :uploaded_files, &(&1 ++ uploaded_files))}
end
attr :page, :integer, required: true
attr :album, Album.Album, required: true
def render(assigns) do
~H"""
<div>
<div>photos</div>
<div>
<%= for entry <- @uploads.photoset.entries do %>
<%= entry.client_name %> - <%= entry.progress %>%
<% end %>
<form phx-submit="save" phx-change="validate">
<%= live_file_input(@uploads.photoset) %>
<button type="submit">Upload</button>
</form>
</div>
</div>
"""
end
end
this crashes by page with
ArgumentError at GET /albums/1Ovxpva
assign/3 expects a socket from Phoenix.LiveView/Phoenix.LiveComponent or an assigns map from Phoenix.Component as first argument, got: %{accept: ".jpg,.jpeg,.png,.webp", __given__: %{accept: ".jpg,.jpeg,.png,.webp"}}You passed an assigns map that does not have the relevant change tracking information. This typically means you are calling a function component by hand instead of using the HEEx template syntax. If you are using HEEx, make sure you are calling a component using:
<.component attribute={value} />
If you are outside of HEEx and you want to test a component, use Phoenix.LiveViewTest.render_component/2:
Phoenix.LiveViewTest.render_component(&component/1, attribute: "value")
Would anyone have a pointer what I am doing wrong? I also tried only one component but it gives the same error. It’s pretty text book implementation so far, and I’m very new to phoenix and elixir.
