Django: Save and restore a form's state using a cookie

懵懂的女人 提交于 2019-12-03 12:45:24
问题 I want to make a form that once submitted, on each next rendering of the form for the same user, the form will be already filled out with the data from the last time the user submitted it. sounds like something that django should have shortcut for - does it have it? if not what would be the easiest way to do it? The best I could come up with is pickeling cleaned_data and saving it as a cookie, recreating the form from it later. 回答1: This already sounds like a good plan. But if there is no

How do I restore a single table from a SQL Server 2005 backup?

耗尽温柔 提交于 2019-12-03 10:33:50
I've got a backup made using the regular SQL Server 2005 backup command. Is there a way to restore just a single table, not the whole DB? Restore the whole database to another machine (or temporary database), then copy the table seems like the easiest to me. This is not natively supported in SSMS but it’s possible using third party tools. Apart from Red Gate (great tools btw) you can try SQL Diff (restore object) and SQL Data Diff (restore data) from ApexSQL. Disclaimer: I’m not affiliated with ApexSQL but we are their customers and use their tools The unit of backup and recovery in SQL Server

How to locate and recover a deleted file

At some stage in the past I had a "foo.txt" which was under Mercurial source control. However it has now been deleted. How can I recover the file when I don't know the last Mercurial revision in which the file was deleted? If you know the exact path for the file, you can do something like : hg log -l 1 path/to/foo.txt This will show you the last changeset where foo.txt was modified, so you will be able to restore the file from this revision. Once you have the right revision, you can simply do : hg revert -r <my revision> path/to/foo.txt hg commit -m "add the foo.txt file again" Using revsets:

Restore SQL Server DB without transaction log

折月煮酒 提交于 2019-12-03 09:18:52
Given a SQL Server 2008 .bak file, is there a way to restore the data file only from the .bak file, without the transaction log ? The reason I'm asking is that the transaction log file size of this database is huge - exceeding the disc space I have readily available. I have no interest in the transaction log, and no interest in any uncompleted transactions. Normally I would simply shrink the log to zero, once I've restored the database. But that doesn't help when I have insufficient disc space to create the log in the first place. What I need is a way to tell SQL Server to restore only the

Saving data in edittext when hitting Back button

限于喜欢 提交于 2019-12-03 08:47:56
So on activity 1 I click a button that takes me to activity 2. In activity 2 I enter some data into an EditText. When I hit the back button on the phone it takes me to activity 1 which is correct but if I hit the activity 1 button again any text that I entered into the EditText is gone. I am sure this is because I am starting a new Intent every time I hit my button and I think I need to be using Flags but I am not certain. Below is my basic MainActivity1 and MainActivity2 without the code I tried that didn't work. **Edit: After exiting the app all saved data needs to be deleted. MainActivity1
