spring boot 2.x, i added springfox-boot-starter 3.0.0 and #EnableOpenApi to use swagger3.
i have following controller
#DeleteMapping("/rate")
public void deleteRate(#ApiParam(value = "dc id") #RequestParam(required = false) Integer dcId,
#ApiParam(value = "rate id")
#RequestParam(required = false) List<Integer> dcrIdList) {
however, for parameter List<Integer> in swagger, it is integer rather than an array/list, it looks like:
it should be multiple inputs such that i can enter multiple values for array/list, right?
how can i input multiple values for list in swagger3? if i type multiple values separated by comma in one input, swagger3 give me error tip.

I am using BeanItemContainer for my Grid. I want to get a unique list of one of the properties. For instance, let's say my beans are as follows:
class Fun {
String game;
String rules;
String winner;
}
This would display as 3 columns in my Grid. I want to get a list of all the unique values for the game property. How would I do this? I have the same property id in multiple different bean classes, so it would be nice to get the values directly from the BeanItemContainer. I am trying to avoid building this unique list before loading the data into the Grid, since doing it that way would require me to handle it on a case by case basis.
My ultimate goal is to create a dropdown in a filter based on those unique values.
There isn't any helper for directly doing what you ask for. Instead, you'd have to do it "manually" by iterating through all items and collecting the property values to a Set which would then at the end contain all unique values.
Alternatively, if the data originates from a database, then you could maybe retrieve the unique values from there by using e.g. the DISTINCT keyword in SQL.
In case anyone is curious, this is how I applied Leif's suggestion. When they enter the dropdown, I cycle through all the item ids for the property id of the column I care about, and then fill values based on that property id. Since the same Grid can be loaded with new data, I also have to "clear" this list of item ids.
filterField.addFocusListener(focus->{
if(!(filterField.getItemIds() instanceof Collection) ||
filterField.getItemIds().isEmpty())
{
BeanItemContainer<T> container = getGridContainer();
if( container instanceof BeanItemContainer && getFilterPropertyId() instanceof Object )
{
List<T> itemIds = container.getItemIds();
Set<String> distinctValues = new HashSet<String>();
for(T itemId : itemIds)
{
Property<?> prop = container.getContainerProperty(itemId, getFilterPropertyId());
String value = null;
if( prop.getValue() instanceof String )
{
value = (String) prop.getValue();
}
if(value instanceof String && !value.trim().isEmpty())
distinctValues.add(value);
}
filterField.addItems(distinctValues);
}
}
});
Minor point: the filterField variable is using the ComboBoxMultiselect add-on for Vaadin 7. Hopefully, when I finally have time to convert to Vaadin 14+, I can do something similar there.
I have identified 3-5 keywords for every requirement in module-A. Each keyword is separated by a comma. Now I want to search every requirement in module-B to see which of them have words that match each of the key words.
Not sure exactly what you're looking for. You might have to specify if none of these solutions I'm about to propose are exactly what you're looking for.
If you're trying to create a filter which displays only objects with those keywords in your current view, you can create an advanced filter by first going to filter (Tools > Filter > Define) and then select the Advanced button on the bottom left of the filter menu that appears.
At this point you can create custom rules for the filter. I would just create an individual rule for each word with the following definition:
Attribute: Object Text
Condition: contains
Value: <insert word here>
Match Case: uncheck
Regular Expression: uncheck
Then select the Add button to add the rule to the list of available rules in the Advanced Options.
At this point you can select multiple rules in the list of available rules and you can AND/OR these rules together to create a custom filter for the view that you want.
So that's for if you're trying to create a custom view with just objects containing specific words.
If you're talking about writing DXL code to automatically spit out requirements that have a particular word in it. You can use the something that looks like this:
Object o
String s
int offset, len
for o in entire (current Module) do
{
if (isDeleted(o)) continue
s = o."Object Text"""
if findPlainText(s, "<insert word here>", offset, len, false)
{
print identifier(o) // or replace this line with however you want to display object
}
}
Hope this is helpful. Cheers!
Edit:
To perform actions on a comma separated list, one at a time, you can use a while loop with some sort of search function that cuts off words one at a time.
void processWord (string someWord, Module mTarget, Object oSource)
{
Object oTarget
string objID = identifier(oSource)
for oTarget in mTarget do
{
if (<someWord in oTarget Object Text>) // edit function as necessary to do this
{
if (oTarget."Exists""" == "")
oTarget."Exists" = objID
else
oTarget."Exists" = oTarget."Exists" "," objID
}
}
}
int offset, len
string searchCriteria
Module mSource = read("<path of source module>", true)
Module mTarget = edit("<path of target module>", true)
Object oSource
for oSource in mSource do // can use "for object in entire(m)" for all objects
{
if (oSource != rqmt) continue // create conditions specific to your module here
searchCriteria = oSource."Search Criteria"""
while (findPlainText(searchCriteria, ",", offset, len, false))
{
processWord(searchCriteria[0:offset-1], mTarget, oSource)
searchCriteria = searchCriteria[offset+1:]
}
}
processWord(searchCriteria, mTarget, oSource) // for last value in comma separated list
This query produces an error No value given for one or more required parameters:
using (var conn = new OleDbConnection("Provider=..."))
{
conn.Open();
var result = conn.Query(
"select code, name from mytable where id = ? order by name",
new { id = 1 });
}
If I change the query string to: ... where id = #id ..., I will get an error: Must declare the scalar variable "#id".
How do I construct the query string and how do I pass the parameter?
The following should work:
var result = conn.Query(
"select code, name from mytable where id = ?id? order by name",
new { id = 1 });
Important: see newer answer
In the current build, the answer to that would be "no", for two reasons:
the code attempts to filter unused parameters - and is currently removing all of them because it can't find anything like #id, :id or ?id in the sql
the code for adding values from types uses an arbitrary (well, ok: alphabetical) order for the parameters (because reflection does not make any guarantees about the order of members), making positional anonymous arguments unstable
The good news is that both of these are fixable
we can make the filtering behaviour conditional
we can detect the category of types that has a constructor that matches all the property names, and use the constructor argument positions to determine the synthetic order of the properties - anonymous types fall into this category
Making those changes to my local clone, the following now passes:
// see https://stackoverflow.com/q/18847510/23354
public void TestOleDbParameters()
{
using (var conn = new System.Data.OleDb.OleDbConnection(
Program.OleDbConnectionString))
{
var row = conn.Query("select Id = ?, Age = ?", new DynamicParameters(
new { foo = 12, bar = 23 } // these names DO NOT MATTER!!!
) { RemoveUnused = false } ).Single();
int age = row.Age;
int id = row.Id;
age.IsEqualTo(23);
id.IsEqualTo(12);
}
}
Note that I'm currently using DynamicParameters here to avoid adding even more overloads to Query / Query<T> - because this would need to be added to a considerable number of methods. Adding it to DynamicParameters solves it in one place.
I'm open to feedback before I push this - does that look usable to you?
Edit: with the addition of a funky smellsLikeOleDb (no, not a joke), we can now do this even more directly:
// see https://stackoverflow.com/q/18847510/23354
public void TestOleDbParameters()
{
using (var conn = new System.Data.OleDb.OleDbConnection(
Program.OleDbConnectionString))
{
var row = conn.Query("select Id = ?, Age = ?",
new { foo = 12, bar = 23 } // these names DO NOT MATTER!!!
).Single();
int age = row.Age;
int id = row.Id;
age.IsEqualTo(23);
id.IsEqualTo(12);
}
}
I've trialing use of Dapper within my software product which is using odbc connections (at the moment). However one day I intend to move away from odbc and use a different pattern for supporting different RDBMS products. However, my problem with solution implementation is 2 fold:
I want to write SQL code with parameters that conform to different back-ends, and so I want to be writing named parameters in my SQL now so that I don't have go back and re-do it later.
I don't want to rely on getting the order of my properties in line with my ?. This is bad. So my suggestion is to please add support for Named Parameters for odbc.
In the mean time I have hacked together a solution that allows me to do this with Dapper. Essentially I have a routine that replaces the named parameters with ? and also rebuilds the parameter object making sure the parameters are in the correct order.
However looking at the Dapper code, I can see that I've repeated some of what dapper is doing anyway, effectively it each parameter value is now visited once more than what would be necessary. This becomes more of an issue for bulk updates/inserts.
But at least it seems to work for me o.k...
I borrowed a bit of code from here to form part of my solution...
The ? for parameters was part of the solution for me, but it only works with integers, like ID. It still fails for strings because the parameter length isn't specifed.
OdbcException: ERROR [HY104] [Microsoft][ODBC Microsoft Access Driver]Invalid precision value

var result = await conn.QueryAsync(sQuery, new { State = state });
WebAPI.Controllers.CustomerController.GetByState(string state) in CustomerController .cs
return await _customerRepo.GetByState(state);
For Dapper to pass string parameters to ODBC I had to specify the length.
var result = await conn.QueryAsync<Customer>(sQuery, new { State = new DbString { Value = state, IsFixedLength = true, Length = 4} });
I have a Grails command object with a list of maps. The map key is intended to be a numeric domain object ID.
class MyCommand {
def grid = [].withDefault { [:] }
}
Data binding to the list/map is working in general because of the dynamic list expansion.
However, in the POST, the map keys are being bound as Strings and I want them to be Longs, as they are when the form is initially populated. I want foo[123] in my map, not foo['123'].
Alternatively I would be satisfied if the [] operators found the correct value given a numeric ID key to look up. In other words, if I could get foo[123] to return the same value as foo['123'], that would work too.
Any way to get this to work the way I want to? Maybe strongly type the map?
Or a better approach?
You can inject the property into the map to convert a String key to Long. For example:
def myMap = [:] << ['1': "name"] << ['Test': "bobo"]
def result = myMap.inject([:]){map, v ->
def newKey = v.key.isNumber() ? v.key.toLong() : v.key
map[newKey] = v.value
map
}
assert myMap['1'] == 'name'
assert result[1L] == 'name'
assert result['Test'] == 'bobo'
I have a results view that displays a list of items.
In some cases, I want to display items where one field matches the query argument. In other cases, I want to display items where another field matches the query argument. And so on.
How can I provide arguments to my controller/view so that it knows what kind of results to get? I could write multiple controllers, but then I get the error that "Type 'MyType' already defines a member called 'MyMethod' with the same parameter type."
Ideally, I could find a way to do this without creating additional routes. Is this possible?
From what I understand from your question you want to do the following:
Reutilize a view, so that you don't have to make one for each query.
Use the same method name on a controller so that you don't have a different url for each query.
You could add an extra parameter to your method so that you can perform a different query depending on the value of the extra parameter:
public class QueryController
{
private enum QueryType
{
TypeA = 0,
TypeB = 1,
TypeC = 2
}
[HttpGet]
public void ShowResults(QueryType type, string criteria)
{
/*
* Code here to make the query using the field you want,
* depending on the "type" parameter e.g.
*
* switch (type)
* {
* case TypeA:
* model = db.Items.Where(x => x.FieldA == criteria);
* break;
* case TypeB:
* model = db.Items.Where(x => x.FieldB == criteria);
* break;
* }
*/
return View(model);
}
}
Another thing, don't worry about the routes, the default route {controller}/{method}/{id} doesn't demand that you have to specify the URLs in that strict way. This is a valid URL for the previous example:
http://www.example.com/App/Query/ShowResults?type=1&criteria=foo
The default MVC binder will use the parameter names in the URL to bind their values to the parameters of your method.
I hope I didn't misunderstood your question.
Good luck!
With MVC, query string values map to parameter values (and Routes are used to create custom mappings).
There are special exceptions though. If a parameter is a FormCollection (which is basically just a Dictionary<string>), then all un-mapped query string values will be passed in.
So, you can create a single Action that takes in all parameters:
// GET: MyController/ViewList?name=aaa&field1=foo&field2=bar
public ActionResult ViewList(string name, FormCollection otherFields) {
foreach (var field in otherFields) {
switch (field.Key.ToLower()) {
case "field1":
// Filter field1 based on field.Value
case "field2":
// Filter field2 based on field.Value
...
}
}
...
}
Similarly, you could also have no parameters, and just use this.Request.QueryString to inspect the query string values. However, I prefer the FormCollection method because it makes it clear that I expect other parameters.
