dccDatePickerRange: DatePickerRange component

In dash: An Interface to the Dash Ecosystem for Authoring Reactive Web Applications

DatePickerRange component

Description

DatePickerRange is a tailor made component designed for selecting timespan across multiple days off of a calendar. The DatePicker integrates well with the Python datetime module with the startDate and endDate being returned in a string format suitable for creating datetime objects. This component is based off of Airbnb's react-dates react component which can be found here: https://github.com/airbnb/react-dates

Arguments

id	Character. The ID of this component, used to identify dash components in callbacks. The ID needs to be unique across all of the components in an app.
start_date	Character. Specifies the starting date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
start_date_id	Character. The HTML element ID of the start date input field. Not used by Dash, only by CSS.
end_date_id	Character. The HTML element ID of the end date input field. Not used by Dash, only by CSS.
end_date	Character. Specifies the ending date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
min_date_allowed	Character. Specifies the lowest selectable date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
max_date_allowed	Character. Specifies the highest selectable date for the component. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
disabled_days	List of characters. Specifies additional days between min_date_allowed and max_date_allowed that should be disabled. Accepted datetime.datetime objects or strings in the format 'YYYY-MM-DD'
initial_visible_month	Character. Specifies the month that is initially presented when the user opens the calendar. Accepts datetime.datetime objects or strings in the format 'YYYY-MM-DD'
start_date_placeholder_text	Character. Text that will be displayed in the first input box of the date picker when no date is selected. Default value is 'Start Date'
end_date_placeholder_text	Character. Text that will be displayed in the second input box of the date picker when no date is selected. Default value is 'End Date'
day_size	Numeric. Size of rendered calendar days, higher number means bigger day size and larger calendar overall
calendar_orientation	A value equal to: 'vertical', 'horizontal'. Orientation of calendar, either vertical or horizontal. Valid options are 'vertical' or 'horizontal'.
is_RTL	Logical. Determines whether the calendar and days operate from left to right or from right to left
reopen_calendar_on_clear	Logical. If True, the calendar will automatically open when cleared
number_of_months_shown	Numeric. Number of calendar months that are shown when calendar is opened
with_portal	Logical. If True, calendar will open in a screen overlay portal, not supported on vertical calendar
with_full_screen_portal	Logical. If True, calendar will open in a full screen overlay portal, will take precedent over 'withPortal' if both are set to true, not supported on vertical calendar
first_day_of_week	A value equal to: 0, 1, 2, 3, 4, 5, 6. Specifies what day is the first day of the week, values must be from [0, ..., 6] with 0 denoting Sunday and 6 denoting Saturday
minimum_nights	Numeric. Specifies a minimum number of nights that must be selected between the startDate and the endDate

show_outside_days	Logical. If True the calendar will display days that rollover into the next month
month_format	Character. Specifies the format that the month will be displayed in the calendar, valid formats are variations of "MM YY". For example: "MM YY" renders as '05 97' for May 1997 "MMMM, YYYY" renders as 'May, 1997' for May 1997 "MMM, YY" renders as 'Sep, 97' for September 1997
display_format	Character. Specifies the format that the selected dates will be displayed valid formats are variations of "MM YY DD". For example: "MM YY DD" renders as '05 10 97' for May 10th 1997 "MMMM, YY" renders as 'May, 1997' for May 10th 1997 "M, D, YYYY" renders as '07, 10, 1997' for September 10th 1997 "MMMM" renders as 'May' for May 10 1997
disabled	Logical. If True, no dates can be selected.
clearable	Logical. Whether or not the dropdown is "clearable", that is, whether or not a small "x" appears on the right of the dropdown that removes the selected value.

className	Character. Appends a CSS class to the wrapper div component.
updatemode	A value equal to: 'singledate', 'bothdates'. Determines when the component should update its value. If 'bothdates', then the DatePicker will only trigger its value when the user has finished picking both dates. If 'singledate', then the DatePicker will update its value as one date is picked.
loading_state	Lists containing elements 'is_loading', 'prop_name', 'component_name'. those elements have the following types: - is_loading (logical; optional): determines if the component is loading or not - prop_name (character; optional): holds which property is loading - component_name (character; optional): holds the name of the component that is loading. Object that holds the loading state object coming from dash-renderer
persistence	Logical | character | numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If 'persisted' is truthy and hasn't changed from its previous value, any 'persisted_props' that the user has changed while using the app will keep those changes, as long as the new prop value also matches what was given originally. Used in conjunction with 'persistence_type' and 'persisted_props'.
persisted_props	List of a value equal to: 'start_date', 'end_date's. Properties whose user interactions will persist after refreshing the component or the page.
persistence_type	A value equal to: 'local', 'session', 'memory'. Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.

Value

named list of JSON elements corresponding to React.js properties and their values
