バージョン1.8のDjango管理者でSelectFilterを使用しています。Django 1.8 SelectFilter2の画像が表示されない
フィルタの画像が表示されません。 https://github.com/darklow/django-suit/issues/469 私はSelectFilter2.jsにハックしてそれを修正助け：この問題は、ここでの最後のポストはちょうどV 1.9 https://code.djangoproject.com/ticket/26394
のためだったとして、これは私のためのソリューションを持っていない以外、この問題のようなビット、
if (typeof admin_static_prefix == 'undefined'){
admin_static_prefix = '/xxxx/static/admin/';
}
これは問題を修正しましたが、現在は環境固有のものであり、本当にいいとは言えません。
私は、admin_static_prefixが正しく渡されなかった理由を調べようとしているコードを追跡しましたが、結局私はそうだと思います。私は、ページが生成されたときに、私が想定している呼び出しがjsに行われたことを見ることさえできます。
<script type="text/javascript">addEvent(window, "load", function(e) {SelectFilter.init("id_tags", "tags", 0, "/xxxx/static/admin/"); });</script>
だから、うまくいくはずですが、何かがうまくいかないようです。
ページ上の別のエラーがあります：
Uncaught TypeError: Cannot read property 'id' of nullinit @ SelectFilter2.js:24(anonymous function) @ (index):547
しかし、私はウィジェットや画像をadmin_static_prefix設定し、一度はので、私は、これは赤ニシンであるかどうかわからない細かい作業します。
以下の参照を簡単にするために、SelectFilter2 JavaScriptが完全にあります。
