The following is a simple implementation of Python + MongoDB auto-incrementing key values. I think this is quite good. now I will share it with you and give you a reference. Let's take a look at it with Xiaobian. Background I recently wrote a test toolbox with a bug record system. I encountered a problem because I used Django and MongoDB in the background, how to implement an auto-increment field. It is v

It's not easy for programmers to remember the names of a lot of class names or class methods. If you want the IDE to be able to automatically complete the code, that will be a great help to our programmers.The Code hints feature in the Eclipse code is turned off by default, only the input "." When the feature is prompted with VS users may not be accustomed to this, VS is the input of any letter will prompt, the following is how to modify the Eclipse configuration, turn on the code automatic prom

One, auto1, the role of autoin general, when assigning the return value of an expression or function to an object, we must know the return type of the expression, but sometimes it is difficult or impossible to know the expression or the return type of the function. This time, We can use the Auto keyword to let the compiler help us parse the expression or the type the function belongs to. Like what:Auto item = val1 + Val2;

The powerful traditional industry is like a vast ocean, it is easy to absorb the new Internet into its own body. But from these traditional industries in the ocean accidentally will evaporate a little steam, when the water vapor hits the internet, they melt into a pearl, or crystal clear or radiant. In some industries, we have seen such pearls, beautiful people such as Ctrip, Art Dragon, 51job, and yet to be further processed and polished such as Sunco real estate, search rooms, Chinese elite,
