I'm trying to build a login page using Golang, but I can't assign specific characters to the form values for username, email, and password.
Found this snippet when I searched for a solution:
if regexp.MustCompile(`^([A-Za-z0-9]{5,})+$`, r.FormValue("username")) == false{
pageinfo.username = "There are disallowed symbols in the field. The allowed characters are: a-zA-Z0-9"
}
The visitor should have shown the pageinfo.username message if he used different characters, but a problem appears:
./user.go:43:54: too many arguments in ca ll to regexp.MustCompile
have (string, string)
want (string)
./user.go:43:76: invalid operation: regexp.MustCompile(`^([A-Za-z0-9]{5,})+$`, r.FormValue("username")) false (mismatched type == s *regexp.Regexp and untyped bool)
make: *** [Makefile:6: main] Error 2
exit status 2
Is there another way to do that?
Note: I am new to using Golang.

As the title say, I have a code like this:
//if i don't use this line r.postform() don't works and return absolute nothing.
//html form works correctly
// I don't need to call r.PostFormValue for every key, just one
fmt.Println(r.PostFormValue("oldpass"))
if r.PostForm.Has("oldpass") && r.PostForm.Has("newpass1") && r.PostForm.Has("newpass2")
{ //if i don't call r.PostFormValue() the program stop before the if }
}
Make no sense to me... Also I remember to have used it without in the past, so I don't think it depend on parsing the value... What could be?

I want to include accented characters in a Sphinx heading such that I will see the following result:
Finalé
I have tried the following strategies:
Use the unicode character directly such as:
Finalé
======
but the character is considered invalid by Docutils.
Also, I have tried using the strip_html specification in conf.py along with the following text:
Finalé
==============
But the text is left unchanged and the HTML entity is passed through.
Can anyone suggest a way of handling accented characters in Sphinx that will work in all situations and where the final output may be HTML or Latex?

I am trying to convert a string to a date time object. The string looks like this
"2016-06-16T23:26:25.252Z"
I have been trying to convert it using DateTime.strptime(str,"'%Y-%m-%dT%H:%M:%S.%L%z") but gives invalid date error.
Do any of you know the issue?
Thanks!
You put an extra quotation mark in the string.
str = "2016-06-16T23:26:25.252Z"
DateTime.strptime(str,"'%Y-%m-%dT%H:%M:%S.%L%z") #=> ArgumentError: invalid date
DateTime.strptime(str,"%Y-%m-%dT%H:%M:%S.%L%z") #=> #<DateTime: 2016-06-16T23:26:25+00:00 ((2457556j,84385s,252000000n),+0s,2299161j)>

I am trying to check if a specific element is included in an output. I run:
results.include? {"_id"=>{"car_id"=>44, "page"=>"5"}, "summarized_time"=>100}
but I get an error:
Syntax error, unexpected =>, expecting '}'
What did I do wrong?
The problem is that the curly brackets in this case are interpreted as start of a block. Just put () around:
results.include?({"_id"=>{"car_id"=>44, "page"=>"5"}, "summarized_time"=>100})

I am new to JDBC and trying following code. Could not find the error in it:
try{
Connection con = ConnectionProvider.getCon();
stmt=con.prepareStatement("insert into create_request values((select count(reqno) from create_request)+1,?,?,?,?,?)");
stmt.setString(1,obj_Leaverequest.getUser_name());
stmt.setString(2,obj_Leaverequest.getLeave_Type());
stmt.setInt(3,obj_Leaverequest.getLeave_Units());
stmt.setString(4,obj_Leaverequest.getLeave_Reason());
stmt.setString(5,"pending");
count=stmt.executeUpdate();
if(count>0){
status=true;
}
}
Update:
If I replace my code like this it works:
String sqQuery="insert into create_request values (?,?,?,?,?,?)";
stmt=con.prepareStatement(sqQuery);
stmt.setString(1,"(select count(reqno) from create_request)+1");
stmt.setString(2,obj_Leaverequest.getUser_name());
stmt.setString(3,obj_Leaverequest.getLeave_Type());
stmt.setInt(4,obj_Leaverequest.getLeave_Units());
stmt.setString(5,obj_Leaverequest.getLeave_Reason());
stmt.setString(6,"pending");
Getters are working fine, I could print their values. I guess I am wrong with the query. Please point out my mistake. Thanks in advance!!
String sqQuery="insert into create_request values (?,?,?,?,?,?)";
stmt=con.prepareStatement(sqQuery);
stmt.setString(1,"(select count(reqno) from create_request)+1");
stmt.setString(2,obj_Leaverequest.getUser_name());
stmt.setString(3,obj_Leaverequest.getLeave_Type());
stmt.setInt(4,obj_Leaverequest.getLeave_Units());
stmt.setString(5,obj_Leaverequest.getLeave_Reason());
stmt.setString(6,"pending");
Check for the "?" prepared statements index . You have 6 , but you need only 5
Hope this helps
