c++ - Subsequent insertion of records with QSqlTableRecord fail after first error -

-

I have problems inserting data into SQLite database by using QSqlTableModel. The table is created like this: 

  QSqlQuery createTblSMS ("Create table sms_tbl (" "Reed bullion tap," "Reditime datite," "Outtime datetime faucet," "Sender text not faucet," "Receiver text tap," "SMS Content text, "" primary key (arrival time, sender, receiver)) ";);

I am including this type of archive: 

  smsModel-> InsertRecord (-1, sms); QString Error = smsModel-> Last error (). Text (); SmsModel- & gt; SubmitAll ();

SMS modal is QSqlTableModel

If I put a value for example then this value (false, zero, '2010-06-30 17:27:55 ',' 075710383 ',' A142140 ',' Top 15 # 2 ') - Record is inserted. For example, if this record is placed after this record (false, zero, '2010-06-30 10:05:29', '075710383', 'one 142140', 'top 15 # 3') - this The record is also inserted.

But if I try to rejoin the record (wrong, tap, '2010-06-30 17:27:55', '075710383', 'one 142140', 'Top 15 # 2 Do ') which is already in the database, the SMS MODEL will give an error like this: "column arrival time, sender, receivers are not unique" unable to get the line - which is expected. Any other subsequent insertions of unique records will fail and the model gives me the same error. Do you have any clue why this is happening?

I went into this issue of two times.

When you are in manual deposit mode, QSqlTableModel does not clean its cache once a subfix fails (this should be done when you send it a record that violates your barriers).

To fix this, you must call the call to remove those pending changes () or call back to return.

Doctors do not make it very clear, but it is there, see:

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
