This explains how to fix the error(must be a category instance) when you try to submit a form with foreign key reference in it. This is specific to Django framework which uses Python. Back end is mysql.
If you have been trading the markets for any length of time, you know that it is not enough to just look at the values of the big index products to see if the market is up or down. Often times there is more going on under the hood than those numbers indicate.
To further gauge the strength of the market, I use 5 tools that can be found in most charting platforms. You will find a link to a pre loaded shared Thinkorswim platform below that you can click on and take a look at these tools.
Before I get into the details of these tools, I will point out that I do not place or manage trades based on these tools. They are simply there for me to stay up to speed with what is going on in the overall market without being glued to the computer screen all day long.

What’s Missing?
To utilise resources in the most efficient way, one must understand the issues that these resources are trying to address. Gathering the information required to make informed decisions is perhaps the best way to deal with the next step in Portable Antiquities, their place in academic research and public heritage value.
Exploring the UK systems and preconceptions, this paper deals with the realities in the field and uses the authors previously gathered information along with statistical analysis that compares the two main processes of artefact collection – detecting and commercial archaeology.
Drawing on a wealth of recent analysis and fieldwork, the purpose will be to reassess the directions taken, and argue for a focussed approach that acknowledges both the benefits and harsh realities when it comes to dealing with portable antiquities collection, sale and recording in the UK.
The final consideration will be to find ways in which to ensure the maximum recoverable knowledge - which includes the views of the primary source of these items; the detecting community, with proactive contact with all relevant bodies and groups to gain a first hand insight, rather than unworkable impositions.

Rapid and Scalable Development with MongoDB, PyMongo, and MingRick Copeland
This talk, given at PyGotham 2011, will teach you techniques using the popular NoSQL database MongoDB and the Python library Ming to write maintainable, high-performance, and scalable applications. We will cover everything you need to become an effective Ming/MongoDB developer from basic PyMongo queries to high-level object-document mapping setups in Ming.
Rapid, Scalable Web Development with MongoDB, Ming, and PythonRick Copeland
In 2009, SourceForge embarked on a quest to modernize our websites, converting a site written for a hodge-podge of relational databases in PHP to a MongoDB and Python-powered site, with a small development team and a tight deadline. We have now completely rewritten both the consumer and producer parts of the site with better usability, more functionality and better performance. This talk focuses on how we're using MongoDB, the pymongo driver, and Ming, an ORM-like library implemented at SourceForge, to continually improve and expand our offerings, with a special focus on how3 anyone can quickly become productive with Ming and pymongo without having to apologize for poor performance.
Architecture | Busy Java Developers Guide to NoSQL | Ted NewardJAX London
2011-11-02 | 03:45 PM - 04:35 PM |
The NoSQL movement has stormed onto the development scene, and it’s left a few developers scratching their heads, trying to figure out when to use a NoSQL database instead of a regular database, much less which NoSQL database to use. In this session, we’ll examine the NoSQL ecosystem, look at the major players, how the compare and contrast, and what sort of architectural implications they have for software systems in general.
Dev Jumpstart: Build Your First App with MongoDBMongoDB
New to MongoDB? This talk will introduce the philosophy and features of MongoDB. We’ll discuss the benefits of the document-based data model that MongoDB offers by walking through how one can build a simple app. We’ll cover inserting, updating, and querying the database of books. This session will jumpstart your knowledge of MongoDB development, providing you with context for the rest of the day's content.
Recent releases of the .NET driver have added lots of cool new features. In this webinar we will highlight some of the most important ones. We will begin by discussing serialization. We will describe how serialization is normally handled, and how you can customize the process when you need to, including some tips on migration strategies when your class definitions change. We will continue with a discussion of the new Query builder, which now includes support for typed queries. A major new feature of recent releases is support for LINQ queries. We will show you how the .NET driver supports LINQ and discuss what kinds of LINQ queries are supported. Finally, we will discuss what you need to do differently in your application when authentication is enabled at the server.
