can a url have commas?
Yes, a URL can contain commas—but with caveats:
https://example.com/items/1,2,3
https://api.example.com/search?q=foo,bar
%2C
), especially in query parameters or when parsing.Need to handle them in code or in a spec?
func (tc *TrackingController) GetLatestActions(ctx context.Context, req types.ControllerRequest) types.ControllerResponse { id := req.HttpRequest.URL.Query().Get(“id”) actions := req.HttpRequest.URL.Query().Get(“actions”)
this go/gin controller must receive actions which are comma separated
Got it. If actions
is expected to be a comma-separated string in the query (e.g. ?actions=click,scroll,hover
), parse it like this:
func (tc *TrackingController) GetLatestActions(ctx context.Context, req types.ControllerRequest) types.ControllerResponse {
id := req.HttpRequest.URL.Query().Get("id")
rawActions := req.HttpRequest.URL.Query().Get("actions")
var actions []string
if rawActions != "" {
actions = strings.Split(rawActions, ",")
}
// Optional: trim spaces
for i := range actions {
actions[i] = strings.TrimSpace(actions[i])
}
// Use `id` and `actions` as needed
// ...
}
%2C
—Go’s net/url
does that automatically.actions
yields an empty slice, not nil, for easier downstream logic.actions
against allowed values early.Let me know if you want this tested or wrapped in a helper.
for _, record := range records { actionText := record.Action if source := record.Source; source != “” && source != “direct” { actionText = fmt.Sprintf(“%s via %s”, record.Action, source) }
elapsed := now.Sub(record.CreatedAt)
when := humanizeTimeAgo(elapsed)
//views = true? -> array of views only
i have available here an array - filters []string) which contains values for the “action” field in result
result := map[string]any{
"action": actionText,
"Location": nil, //TODO: add location
"when": when,
}
result must contain only those “action”s where the actionText value is a member of the filters, if its not in the filters , don’t append
results = append(results, result)
}
return results, nil # ChatGPT To filter `actionText` against `filters []string`, add a check before appending:
import "slices" // Go 1.21+; otherwise use a helper for contains()
for _, record := range records {
actionText := record.Action
if source := record.Source; source != "" && source != "direct" {
actionText = fmt.Sprintf("%s via %s", record.Action, source)
}
elapsed := now.Sub(record.CreatedAt)
when := humanizeTimeAgo(elapsed)
// Filter check: skip if not in filters
if len(filters) > 0 && !slices.Contains(filters, actionText) {
continue
}
result := map[string]any{
"action": actionText,
"Location": nil, // TODO: add location
"when": when,
}
results = append(results, result)
}
func contains(slice []string, val string) bool {
for _, v := range slice {
if v == val {
return true
}
}
return false
}
Want to support regex or partial match instead of exact match?
slices undefined
Right—slices
is from Go 1.21+. If you’re on an earlier version, use a manual helper:
func contains(slice []string, val string) bool {
for _, v := range slice {
if v == val {
return true
}
}
return false
}
if len(filters) > 0 && !contains(filters, actionText) {
continue
}
Let me know if you want filters
to be case-insensitive or matched against record.Action
instead of actionText
.
i’m on go 1.23 do i need to import slices?
Yes—even in Go 1.23, you still need to import the slices
package explicitly:
import "slices"
It’s in the standard library as of Go 1.21, but not pre-imported automatically.
Use like:
if len(filters) > 0 && !slices.Contains(filters, actionText) {
continue
}
You’re good to go.

consider this function and make the following test pass, give only the relevant/changed bits of code
Sure—please provide the test you want to make pass. Once I see the test, I’ll give you the minimal code changes needed.

})
} } # ChatGPT Your function signature is missing the `filters []string` argument required by the current implementation. The test calls:
got, err := ts.GetLatestActions(context.Background(), tc.args.campaignId, tc.args.top)
But your method requires:
GetLatestActions(ctx context.Context, campaignId string, top int, filters []string)
Update this line in the test:
got, err := ts.GetLatestActions(context.Background(), tc.args.campaignId, tc.args.top)
Change to:
got, err := ts.GetLatestActions(context.Background(), tc.args.campaignId, tc.args.top, nil)
That’s it. No change needed in the function or setup logic unless you’re testing filtering behavior specifically.
Want to add a case that exercises filtering?
for _, record := range records { actionText := record.Action if source := record.Source; source != “” && source != “direct” { actionText = fmt.Sprintf(“%s via %s”, record.Action, source) }
elapsed := now.Sub(record.CreatedAt)
when := humanizeTimeAgo(elapsed)
//views = true? -> array of views only
// Filter check: skip if not in filters
if len(filters) > 0 && !slices.Contains(filters, actionText) {
continue
}
–> this isn’t working here the filters is an array like “filters”:[“share”,”view”,”sign”] and the actionText is a string “view via ShareLink” or “Share via Share button”, so the filteration should check if the any of the given filters in the array is a substring of the actionText, case is irrelevant
result := map[string]any{
"action": actionText,
"Location": nil, // TODO: add location
"when": when,
"user_name": record.MemberName,
}
results = append(results, result)
} # ChatGPT Got it—you want **case-insensitive substring matching** between each `actionText` and the `filters` array. Replace the `slices.Contains(...)` check with a custom match.
if len(filters) > 0 && !slices.Contains(filters, actionText) {
continue
}
if len(filters) > 0 && !matchesAnyFilter(actionText, filters) {
continue
}
func matchesAnyFilter(text string, filters []string) bool {
text = strings.ToLower(text)
for _, f := range filters {
if strings.Contains(text, strings.ToLower(f)) {
return true
}
}
return false
}
Now it will include results where any filter
appears anywhere in actionText
, ignoring case. Example:
filter = "view"
matches actionText = "View via Social"
filter = "share"
matches actionText = "shared via Email"
Want to turn this into a regex filter later? Easy lift.
