  • Python: Cannot concatenate str and NoneType objects

    - by Chase Higgins
    sql = """ INSERT INTO [SCHOOLINFO] VALUES( '""" + self.accountNo + """', '""" + self.altName + """', '""" + self.address1 + """', '""" + self.address2 + """', '""" + self.city + """', '""" + self.state + """', '""" + self.zipCode + """', '""" + self.phone1 + """', '""" + self.phone2 + """', '""" + self.fax + """', '""" + self.contactName + """', '""" + self.contactEmail + """', '""" + self.prize_id + """', '""" + self.shipping + """', '""" + self.chairTempPass + """', '""" + self.studentCount + """' ) """; I have the following code and Python keeps throwing the error that it cannon concatenate strings and nonetype objects. The thing is I have verified every variable here is in fact a string and is not null. I have been stuck on this for quite some time today, and any help would be greatly appreciated.

  • sending a selected value from a dropdownlist to a servlet with xhr

    - by kawtousse
    I am trying to send the clicked value of a dropdown list to my servlet to run a SQL query using the value received. To do it I am using Ajax like that: function showProject(prj) { xmlhttp = GetXmlHttpObject(); if (xmlhttp == null) { alert ("Browser does not support HTTP Request"); return; } var url = "ServletxmlGenerator.java"; idprj = prj.options[prj.selectedIndex].value; url = url + "?idprj=" + idprj; xmlhttp.onreadystatechange = stateChanged; xmlhttp.open("GET",url,true); xmlhttp.send(null); } The servlet when String projectcode=(String) request.getParameter("idprj"); returns null. When I select a value from the JSP that construct the dropdown list and from which the function showProject is handled the same thing is happned. It returns always null. So the parameter(idprj) is not passed anyway. How can I handle with this. I need to send the selected value to the servlet to run my SQL query.

  • select random value from each type

    - by Joseph Mastey
    I have two tables, rating: +-----------+-----------+-------------+----------+ | rating_id | entity_id | rating_code | position | +-----------+-----------+-------------+----------+ | 1 | 1 | Quality | 0 | | 2 | 1 | Value | 0 | | 3 | 1 | Price | 0 | +-----------+-----------+-------------+----------+ And rating_option +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 2 | 1 | 2 | 2 | 2 | | 3 | 1 | 3 | 3 | 3 | | 4 | 1 | 4 | 4 | 4 | | 5 | 1 | 5 | 5 | 5 | | 6 | 2 | 1 | 1 | 1 | | 7 | 2 | 2 | 2 | 2 | | 8 | 2 | 3 | 3 | 3 | | 9 | 2 | 4 | 4 | 4 | | 10 | 2 | 5 | 5 | 5 | | 11 | 3 | 1 | 1 | 1 | | 12 | 3 | 2 | 2 | 2 | | 13 | 3 | 3 | 3 | 3 | | 14 | 3 | 4 | 4 | 4 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I need a SQL query (not application level, must stay in the database) which will select a set of ratings randomly. A sample result would look like this, but would pick a random value for each rating_id on subsequent calls: +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 8 | 2 | 3 | 3 | 3 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I'm totally stuck on the random part, and grouping by rating_id has been a crap shoot so far. Any MySQL ninjas want to take a stab? Thanks, Joe

  • Correct usage of Voldemort as key-value pair?

    - by zengr
    Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.

  • Django DecimalField returns "None" instead of empty value

    - by Ed
    Is there a way to force django to display nothing instead of "None" for a Decimal Field that's been left blank? In my template, I show a list of all the values for a particular field. Each value is hyperlinked to a page that displays the results of a query filtered on that value. But because there are some entries with null value, my list includes actual DecimalField entries and "None" for all those that are empty. When a user clicks on None, django throws a validation error because you cannot query a DecimalField using a string. I could write if statements checking all instances of decimal fields for Nones and skipping them, but that is far from an elegant solution. Any advice? This is one part of the code, though there are other templates that derive the None value in slightly different manners: {% for item in choices %} <a href={% url app_views.field_choice item %}>{{ item }}</a><br> {% endfor %}

  • GAE Datastore: persisting referenced objects

    - by David
    Two "I'm sorries" to begin with: 1) I've looked for a solution (here, and elsewhere), and couldn't find the answer. 2) English is not my mother tongue, so I may have some typos and the sort - please ignore them. To the point: I am trying to persist Java objects to the GAE datastore. I am not sure as to how to persist object having ("non-trivial") referenced object. That is, assume I have the following. public class Father { String name; int age; Vector<Child> offsprings; //this is what I call "non-trivial" reference //ctor, getters, setters... } public class Child { String name; int age; Father father; //this is what I call "non-trivial" reference //ctor, getters, setters... } The name field is unique in each type domain, and is considered a Primary-Key. In order to persist the "trivial" (String, int) fields, all I need is to add the correct annotation. So far so good. However, I don't understand how should I persist the home-brewed (Child, Father) types referenced. Should I: Convert each such reference to hold the Primary-Key (a name String, in this example) instead of the "actual" object. So, Vector<Child> offsprings; becomes Vector<String> offspringsNames; ? If that is the case, how do I handle the object at run-time? Do I just query for the Primary-Key from Class.getName, to retrieve the refrenced objects? Convert each such reference to hold the actual Key provided to me by the Datastore upon the proper put() operation? So, Vector<Child> offsprings; becomes Vector<Key> offspringsHashKeys; ? I would very much appreciate all kinds of comments. I have read ALL the offical relevant GAE docs/example. Throughout, they always persist "trivial" references, natively supported by the Datastore (e.g. in the Guestbook example, only Strings, and Longs). Many thanks, David

  • knockout bind text label to dropdown value selected option text

    - by Adam Levitt
    Is there a simple way to bind the textbox of a div to change based on the text value of the selected option in a dropdown on the same page? <div data-bind="text: dropdownValue"></div> <select> <option value="1">Value1</option> <option value="2">Value2</option> </select> Please note, I don't want to put the values into the select element using javascript. I'd like to bind to the value straight from the HTML. I can also include jQuery to make it work.

  • VBS Script for modifying multi-value Active Directory display specifier

    - by sh-beta
    Following the howto Extending the Active Directory Schema To Track Custom Info I'm able to setup a single-value schema attribute that is easily changeable via a context menu in ADUC. Multi-value schema attributes get considerably more complicated. Say (for the sake of argument) my value is "Projects" and each user may be a list as many projects as necessary. Following is a sad little script that will set Project to a single value: Dim oproject Dim oUser1 Dim temp1 Set oproject = Wscript.Arguments Set oUser1 = GetObject(oproject(0)) temp1 = InputBox("Project: " & oUser1.project & vbCRLF & vbCRLF & "Project") if temp1 <> "" then oUser1.Put "project",temp1 oUser1.SetInfo Set oUser1 = Nothing Set oproject = Nothing Set temp1 = Nothing WScript.Quit How can I modify this to allow, assign, and modify multiple values?

  • Richfaces a4j achtionparam set null value

    - by Jurgen H
    I am trying to reset some values in a form using the a4j:actionParam tag. But it seams that null values never arrive in the target bean. The converter receives it correctly, returns null, but it is never set in the bean. The target is to fill in the start and endDate for different predefined values (last week, last month etc). For the "This week" value, the endDate must be reset to null. <rich:menuItem value="Last week"> <a4j:support event="onclick" reRender="criteriaStartCalendar,criteriaEndCalendar"> <a4j:actionparam name="startDate" value="#{dateBean.lastWeekStart}" assignTo="#{targetBean.startDate}" /> <a4j:actionparam name="endDate" value="#{dateBean.lastWeekEnd}" assignTo="#{targetBean.endDate}" /> </a4j:support> </rich:menuItem>

Something like: var o = s.parent; Is this somehow possible?

  • Identity column SQL Server 2005 inserting same value twice

    - by DannykPowell
    I have a stored procedure that inserts into a table (where there is an identity column that is not the primary key- the PK is inserted initially using the date/time to generate a unique value). We then use SCOPEIDENTITY() to get the value inserted, then there is some logic to generate the primary key field value based on this value, which is then updated back to the table. In some situations the stored procedure is called simultaneously by more than one process, resulting in "Violation of PRIMARY KEY constraint..." errors. This would seem to indicate that the identity column is allowing the same number to be inserted for more than one record. First question- how is this possible? Second question- how to stop it...there's no error handling currently so I'm going to add some try/ catch logic- but would like to understand the problem fully to deal with properly

  • Jquery Show Fields depending on Select Menu value but on page load

    - by Tim
    Hello, This question refers to the question http://stackoverflow.com/questions/835259/jquery-show-hide-fields-depening-on-select-value <select id="viewSelector"> <option value="0">-- Select a View --</option> <option value="view1">view1</option> <option value="view2">view2</option> <option value="view3">view3</option> </select> <div id="view1"> <!-- content --> </div> <div id="view2a"> <!-- content --> </div> <div id="view2b"> <!-- content --> </div> <div id="view3"> <!-- content --> </div> $(document).ready(function() { $.viewMap = { '0' : $([]), 'view1' : $('#view1'), 'view2' : $('#view2a, #view2b'), 'view3' : $('#view3') }; $('#viewSelector').change(function() { // hide all $.each($.viewMap, function() { this.hide(); }); // show current $.viewMap[$(this).val()].show(); }); }); When I select the 2nd item in the menu it shows the corresponding field. The exception to this is when the on page load the select menu already has the 2nd menu item selected, the field does not show. As you may be able to tell, I am new to jquery and could definetly use some help with adjusting this code so that the selected item's field is shown on page load. Thanks, Tim

  • AdvancedDataGrid dynamic text Value Coloring - ItemRenderer problem

    - by sri
    In my AdvancedDataGrid, I am adding dynamic values to cells by dragging a cell value to other cells. While copying, I am setting the value to listData and setting the Red color to the value in ItemRenderer. Everything is working fine, but when I scroll down/up, the values remains in the cells where thay are supposed to be(as I am setting to listData) but the coloring behaves wierd(as I am trying to set the color in ItemRenderer). I don't want to store the color of the value, but I should be able to see the dynamically created values in Red color. Is there a way, I can do this? Do I need to set the color to actual dataprovider object and then check in ItemRenderer? Can anyone help me with this? public class CustomItemRenderer extends AdvancedDataGridItemRenderer { private var _isDynamicValue:Boolean; .... .... //_isDynamicValue is set to true if the value is dynamic if(_isDynamicValue && listData.label) { setStyle("color", 0xFF0000); setStyle("fontWeight", "bold"); } else { setStyle("color", 0x000000); }

  • linq NullReferenceException while checking for null reference

    - by Odrade
    I have the following LINQ query: List<FileInputItem> inputList = GetInputList(); var results = from FileInputItem f in inputList where ( Path.GetDirectoryName(f.Folder).ToLower().Trim() == somePath || Path.GetDirectoryName(f.Folder).ToLower().Trim() == someOtherPath ) && f.Expression == null select f; Every time this query is executed, it generates a NullReferenceException. If I remove the condition f.Expression == null or change it to f.Expression != null, the query executes normally (giving the wrong results, of course). The relevant bits of FileInputItem look like this: [Serializable] public class FileInputItem { [XmlElement("Folder")] public string Folder { get; set; } [XmlElement("Expression")] public string Expression { get; set; } /*SNIP. Irrelevant properties */ } I'm new to LINQ to objects, so I'm probably missing something fundamental here. What's the deal?

I also got the error in my immediate window: *Warning: The Value expression for the textrun ‘Name_1.Paragraphs[0].TextRuns[0]’ contains an error: The specified operation is not valid.
