জাঙ্গো ১.৪ এ আমার একটি ত্রুটি বার্তা রয়েছে:
অভিধান আপডেট ক্রম উপাদান # 0 এর দৈর্ঘ্য 1 রয়েছে; 2 প্রয়োজন হয়
[Edit]
আমি যখন টেমপ্লেট ট্যাগটি ব্যবহার করার চেষ্টা করেছি তখন এটি ঘটেছিল: মানগুলির জন্য% v এর জন্য `{%:

আমি যখন কোনও হস্টোর ক্যোয়ারসেটে অ্যাক্সেস করার চেষ্টা করি তখন এটিও ঘটে:

কোডটি হ'ল:

if tmp.count() > 0:
item_id = tmp[0].id,
আমি শুধু মানটি অ্যাক্সেস করার চেষ্টা করছি। আমি "আপডেট ক্রম" বার্তাটি বুঝতে পারি না। আমি যখন hstore ক্যোরিসেটের পরিবর্তে কার্সার ব্যবহার করি তখন ফাংশনটি কাজ করে। ত্রুটিটি টেমপ্লেট রেন্ডারিংয়েও আসে। আমি কেবল পুনঃসূচনা করেছি uwsgi
এবং সবকিছু ভালভাবে কাজ করে তবে ত্রুটিটি পরে ফিরে আসে।

কারও ধারণা আছে?

যদিও এটি হয় নাdict([('A',"b")])
