问题 I have some problems while implementing filters in mongodb using morphia POJO mapper. In my class (for example SampleClass ), when i try to access the fields of an @Entity class (in our case it's Person ), I find the field access works fine, using dot notation for general fields like int, string, maps or direct embedded objects.

问题 I need to assign data field (component of another field symbol) to field-symbol in a several places of code. For the sake of reusability I decided to encapsulate this code in procedure, but I cannot understand how to pass field-symbols into this procedure. LOOP bseg ASSIGNING <bseg> ... PERFORM assigning USING <bseg> CHANGING <wrbtr>. ... ENDLOOP. FORM assigning USING <bseg> TYPE bseg CHANGING <wrbtr> TYPE bseg-wrbtr IF ... some logic here ASSIGN <bseg>-wrbtr TO <wrbtr>. ELSE ASSIGN <bseg>

问题 I am creating a checkout page that requires the client to fill out his personal information as well as his credit card details (this part using stripe). I was wondering, what is the best way to check whether the fields are filled up or not? Shall I do it in the processingPayment.php that $_POSTs the fields and processes payment, and in case the fields were not filled, I would redirect back to checkout? Or is it a better idea to use js to check on the spot before submitting the form? if in the

问题 I have a model called Fattura, and I would like to set the default value of the field "printable" to a string that includes the value of the field "numero". But I have the error that link_fattura has less arguments, but if I add default=link_fattura(self) I have an error because self is not defined. How can I solve this issue? class Fattura(models.Model): def link_fattura(self, *args, **kwargs): return u"http://127.0.0.1:8000/fatture/%s/" % (self.numero) data = models.DateField() numero =

问题 I use iTextSharp to rename PDF form field. The old field names and the new replacement names are entered in a text box (comma separated). My code then loops through each line, grabs the old field name, looks for the field in the PDF and renames it to the new field. Finally, a new PDF is created from the old PDF, and all of the fields in the new PDF will have the new names. My problem is that I can't seem to rename the PDF fields which contain a period in the field name (e.g. First.Name). Is

问题 I'm trying to figure out how to iterate through a document and pull all form fields and insert them into a new text file. I'm working through it trying to find examples of the functions I'm going to need and I'm not coming up with a lot of information. Maybe I'm not searching properly though. Here's what I've written so far. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using

问题 Suppose I have an StoredProcedure that returns a unique row corresponding to a table with columns "Name" and "Surname". I want the report to show: Name: NameField Surname: SurnameField Where the "NameField" and "SurnameField" are the fields returned by the StoredProcedure. The special requirement, is that if "SurnameField" is empty or null, then I don't want to show the "Surname: SurnameField". How can I achieve this? The only thing that I thought is breaking the storedprocedure in two, one
